Menschheitshoffnung semantic web. Wie das semantische Web unser Leben wieder lebenswert macht.

Am 6. August 1991 veröffentlichte Web-Gründer Tim Berners-Lee den Source Code, aus dem das WWW entstand, in der alt.hypertext news group. Fazit nach 15 Jahren. Bei aller technischen Fortentwicklung treiben wir eigentlich immer noch wie 2001-Astronaut David Bowman in einem Trümmer-Universum aus häßlichen Googleresultlisten, blinkenden Werbebannern und Spamtexten. Web-Gründer Berners-Lee ist derweil, wahrscheinlich aus schlechtem Gewissen, schon bei der Entwicklung der nächsten Evolutionsstufe des Internet: dem semantischen Web (engl. semantic web). Grundidee des semantischen Webs ist es, Informationen nicht nur strukturell zu ordnen wie in HTML, sondern die bereitgestellten Informationen auch inhaltlich zu kategorisieren. Eine schwierige und weit reichende Aufgabe, die wir als Internetnutzer auf keinem Fall (wir erinnern an die endlose Rechtschreibreform) einem kleinen Kreis von Experten oder gar dem allgegenwärtigen "Markt" überlassen sollten. Daher sei hier die FICC (Free Initiative for Content Categorisation - http://ficc.wetpaint.com) vorgestellt, eine unabhängige Initiative, die sich am 6. August diesen Jahres am ZÜRN (ZÜrich institute for Retarded Norms) gegründet hat, und die bereits wichtige Vorarbeiten für einen noch zu entwerfenden Standard der semantischen Kategorisierung geleistet hat. Einige der vorläufigen Ergebnisse seien hier zur weiteren Diskussion vorgestellt.

Tags
Fast jeder kennt die berühmten HTML-Tags, mit denen auch diese Website hier zusammengehalten wird. In HTML sind Tags in eckige Klammern eingefasst. So kennzeichnet ein <h1> dass der folgende Text als Headline der Ebene 1 aufzufassen ist. Beendet wird ein Tag durch ein dem Tagwort vorangestelltes "/". Somit beendet </h1> die Headline. Der dann folgende Text wird nicht mehr als Überschrift aufgefasst.

Das gleiche Prinzip soll für semantische Tags gelten. Contentproduzenten, Redaktionen, Websitebetreiber und Internetnutzer können damit Inhalte kennzeichen, die ein noch zu entwickelnder semantischer Browser interpretieren wird. Ein semantische Browser unterstützt das durch übermäßiges Internetsurfen ohnehin geistig geschwächte Individuum beim Verarbeiten und Verstehen der über das Netz vermittelten Informationen. Durch relative einfache Operationen wie Streichen und Ersetzen kann ein semantischer Browser die Produktivität und Lebensfreude eines Internetnutzers erheblich steigern.

Die semantischen Tags - eine vorläufige und offene Liste des f.i.c.c

<COPYPASTE> </COPYPASTE>
wegen der enormen Wichtigkeit, geradezu Allgegenwart kopierter Informationen auch in der Kurzform <CP> </CP> verfügbar. Kennzeichnet, dass die eingeschlossene Information nicht dem Wissen oder der Erfahrung des Autors entspricht, sondern per Copy und Paste aus einer frei zugänglichen Quelle entnommen wurde.

<DEHYPE > </DEHYPE>
Reduziert besonders häufig erwähnte Begriffe auf ein erträgliches Maß. Die Voreinstellung halbiert die Frequenz besonders nerviger Dauerthemen wie z.B. "Krankenkassenreform" "Hartz IV" oder "Web 2.0".
Mit dem Shrink-Modifier kann festgelegt werden, um wieviel Prozent Berichte über den Hype heruntergedampft werden.

Beispiel:

<DEHYPE Shrink=10%> Web 2.0</DEHYPE>
zeigt nur jeden 10. Bericht über Web 2.0 an.

<KRASS> </KRASS>
Kennzeichnet syntaxlose und häufig auch inhaltsleere Aussagen der Jugendsprache wie: "Ey alder weissu" und ersetzt sie durch gängige Begriffe der deutschen Hochsprache.

Beispiel:

<KRASS> Ey alder, krass weissu? </KRASS>

könnte durch einen semantischen Browser übersetzt werden.

"Hallo alter Freund, das ist wirklich erstaunlich, findest du nicht auch?"

<GRASS> </GRASS>
Günter Grass-Tag, blendet alle Berichte und Enthüllungen über Günter Grass, wie sämtliche außerliterarischen Selbstaussagen von Günter Grass systematisch aus. Im "default mode" des semantischen Browsers für alle nach 1970 Geborenen, im "strict mode" für alle Nutzer.

<HASTALAVISTA> </HASTALAVISTA>
Addiert in Berichten über das endgültige Erscheinen der neuen Betriebssystemversion VISTA automatisch zum angegebenen Datum 6 Monate.

<HASTALAVISTA> Oktober 2006 </HASTALAVISTA>

<SPAMPEOPLE> </SPAMPEOPLE>
Nach dem erfolgreichen Test des <NOFRIEDMANN> -Tags wurde dieses auf eine frei konfigurierbare Liste erweitert und in Anlehnung an eine Idee des Autors Wiglaf Droste in <SPAMPEOPLE> umbenannt. Das Tag filtert nun mediale Dauernervensägen aus allen Wort-, Bild-, Audio- und Video-Beiträgen, die über das Internet übertragen werden. Aufgrund des ständigen Zustroms neuer Nervensägen gliedert sich das Tag in eine Defaultliste, die allgemein anerkannte Nervensägen enthält, und eine frei konfigurierbare Zusatzliste, die von Contentproduzenten, Nachrichtenagenturen, Websitebetreibern und individuellen Internetnutzern erstellt und gepflegt werden kann.

In aktuell gültigen RFC-Version ZÜRN-201 vom 19.8. 2006 ist die Defaultliste der Spampeople vorbelegt mit:
DIETER BOHLEN, GUIDO WESTERWELLE, CLAUDIA ROTH, GUENTER JAUCH, DETLEF D. SOEST

Durch den IGNORE Modifier kann die Liste auch nutzerseitig beliebig erweitert werden:

Beispiel:
IGNORE="Merkel, Münte*, Yvonne Catterfield, André Rieux, Ackermann"

<MEM> </MEM>
Zeigt den seltenen Fall an, dass diese Information aus dem Gedächtnis und der Erfahrung des Autors herrührt und es sich nicht um eine Second-Hand-Information handelt, die der Autor "irgendwo gelesen", sprich kopiert hat.

<NOPOP> </NOPOP>
Blendet alle Äußerungen und literarischen Beiträge von so genannten Popliteraten wie Christian Kracht, Benjamin von Stuckradt-Barre und Alexander von Schönburg aus.

Mit dem Zusatz "IGNORE=girlies" werden zudem Beiträge, Berichte über und Photos von Alexa Henning von Lange und Juli Zeh entfernt.

<IGNOREDARWIN> </IGNOREDARWIN>
Zeitgenossen, deren Zeitgenossenschaft sich dadurch kennzeichnet, dass sich lediglich ihre sterblichen Überreste im 21. Jahrhundert aufhalten, können mit diesem Tag alles Wissen, das nach dem 22. November 1859, dem Erscheinungstag der "Origin of species" von Charles Darwin, veröffentlicht wurde, ausblenden.

Mit dem Zusatz "REPLACE= "bible" werden die innerhalb der Tags befindlichen Informationen durch entsprechende Passagen der Bibel ersetzt.

Im Pic-Mode "PIC=0" werden auch Abbildungen, die die Evolutionstheorie unterstützen unterdrückt, bzw. durch "PIC=1" durch durch Abbilder russischer Ikonen oder verletzende Karikaturen ersetzt. Siehe Beispiel unten.

durch <IGNOREDARWIN PIC = "1">

<BORIS> </BORIS>
ersetzt in der nicht abreißenden Berichterstattung über die ständig wechselnden Liebschaften des Ex-Tennisstars die Namen der jeweils "Neuen" durch "aktuelle Gespielin".

<SLIM> </SLIM>
Kann von Personen, die stark zugenommen haben, verwendet werden, um Bilder, auf denen Sie breiter als hoch sind, zu ersetzen durch andere Bilder, auf denen Sie noch schlank und rank sind. Fortentwickelung des <JOSCHKA>-Tags .

<DUDEN> </DUDEN>
ersetzt alle eingeklammerten deutschsprachigen Texte, so lange durch die Schreibweise des Dudens von 1902 bis sich Verlage, durchgeknallte Rechtschreibreformer und Sonderpädagogen und profitgeile Wörterbuchverlage auf eine Schreibweise geeinigt haben. Wird bei Personen über 40 durchgängig ohne Endtag verwendet.

<NOLINK> </NOLINK>
Unterbindet einen Link von einer ungewünschten Seite auf die benannte Seite. Wer möchte sich schon auf Seiten mit Namen wie Jauchetaucher.de gelinkt sehen.

<NONAIDOO> </NONAIDOO>
In MP3 Tags und in Audiostreams verwendbares Tag, das den Hörer von sämtlichen Lautäußerung und Reimversuchen des "Erlösers" Xavier (sprich: Savior) Naidoo erlöst. Durch das Replace-Tag ist einstellbar, welches akustische Ersatzmaterial stattdessen abgespielt wird.

REPLACE = ""
- Stille, die man da zu nutzt, einmal selbst über Gott und die Welt nachzudenken.

REPLACE= "wald"
- Vogelzwitschern aus einem Wald bei Mannheim .

REPLACE= "authentic"
- ersetzt weichgespültem Erleuchtungspop in schlechtem Deutsch durch echten Soul von Curtis Mayfield.

<WELLNESS> </WELLNESS>
Kann als einzige Klammer ohne Endtag verwendet werden, so dass alle das persönliche Wohlbefinden störende Berichte, Photos und Kommentare, für alle folgenden Dokumente auf unbestimmte Zeit ausgeblendet werden, solange bis das </WELLNESS>-Tag auftaucht.

Noch umstritten sind zwei radikale Fortentwicklungen des <WELLNESS>-Tags, das <ZEN>-Tag und das <IGNOREALL>-Tag.

<ZEN></ZEN> synonym zu <IGNOREALL> </IGNOREALL>
Blendet sämtliche textliche und multimediale Informationen aus. Im usermode sieht der Nutzer unabhängig von der angesteuerte Website ein leeres Browserfenster.

RFC - Request for comments
Diese Liste ist, wie bereits erwähnt, sehr vorläufig und kann nur einen kleinen Einblick in die Theorie des semantischen Netzes geben. Das ficc hat am ZÜRN ein WIKI aufgesetzt, um weitere Beiträge der Internetnutzer für einen ersten Standard-Draft zu sammeln.

Unter http://ficc.wetpaint.com kann jeder Internetnutzer dazu beitragen. Die Initiatoren hoffen, damit der Menschheit Desaster wie einen Browserkrieg, den VHS-Standard und die Deutsche Rechtschreibreform zu ersparen.

Eric Klepptenberger ist Gründer des ficc und betreibt nach einem 16-semestrigen Studium der analytischen Philosophie zusammen mit ein paar Freunden eine Joggingwebsite.

kleppten — Fri, 01 Sep 2006 07:30:09 CDT

This article is about the information technology term. For other uses, see Tag (disambiguation). A tag is a keyword or descriptive term associated with an item as means of classification by means of a folksonomy. Tags are usually chosen informally and personally by the author/creator of the item — i.e. not usually as part of some formally defined classification scheme. Tags are typically used in dynamic, flexible, automatically generated internet taxonomies for online resources such as computer files, web pages, digital images, and internet bookmarks (both in social bookmarking services, and in the current generation of web browsers - see Flock and Mozilla Firefox 2.0x). For this reason, "Tagging" has become associated with the Web 2.0 movement. Typically, an item will have one or more "tags" associated with it, as part of some automated classification software or system. The software will provide links to other items that share that keyword tag, or even to specified collections of tags. This allows for multiple "browseable paths" through the items which can quickly and easily be altered by the collection's administrator, with minimal effort and planning. For example

A web page hosted on a web server or blog server which supports tagging, might have the tags Baseball, Red Sox, Tickets, Away Games (tags can be more than one word), and Discounts. A human reader can probably tell the purpose of the page by quickly scanning the list of tags. Typically, the server would display the tags in a list on that page, with each tag displayed as a web link leading to an index page listing all web pages which use that tag. This allows a reader to locate quickly all pages which have been associated with the term Red Sox. If the server supports tag searching, a reader would be able to find all pages that use a particular set of tags, such as Red Sox and Tickets.

If the page's author wishes to reclassify the page, all that is required is for them to change the list of tags. In this case, the author could add the tags Blue Jays, and Paypal to their page. All connections between pages are automatically tracked and updated by the server software. There is no need to relocate the page within a complex hierarchy of categories.

While using tags in such an organizational system is flexible and easy, tagging is not without its drawbacks. Typically there is no information about the meaning or semantics of a tag. For example, the tag "apple" might refer to the fruit, Apple Computer, the Beatles' music label, or Gwyneth Paltrow's baby. This lack of semantic distinction in tags can lead to inappropriate connections between items. Additionally, selection of "tag terms" is highly individualistic. Different people may use drastically different terms to describe the same concept: for example items related to a version of Apple Computer's operating system might be tagged both "OSX", "Tiger", and possibly many other terms. Users of tagging systems must make judgements, based on the number of connections and the choices of "tag terms", whether possible connections between items are valid for their interests. Tag classification, and the concept of connecting sets of tags between web/blog servers, has lead to the rise of folksonomy classification over the internet, the concept of social bookmarking, and other forms of social software. Larger-scale folksomonies tend to address some of the problems of tagging, as astute users of tagging system will monitor/search the current use of "tag terms" within these systems, and tend to use existing tags in order to easily form connections to related items. In this way, evolving folksomonies define a set of tagging conventions through eventual group consensus, rather than by use of a formalized standard. Although "tagging" is often promoted as an alternative to organization by a hierarchy of categories, more and more online resources seem to use a hybrid system, where items are organized into broad categories, with finer classification distinctions being made by the use of tags.

[edit]

Other forms of categorization

Hierarchy - not always applicable, but often more accurate
Ordered list - seldom applicable for large object sets
Network - Always applicable, but may result in enormous taxonomies to be able to define all types of relations

[edit]

Syntax

Some tagging systems provide a single text box to enter textual tags. To be able to tokenize the string, a separator must be used. A popular separator is the space character. To enable the use of separators in the tags, a system may allow for higher-level separators (such as quotation marks) or escape characters. Systems can avoid the use of separators by allowing only one tag to be added to each input widget at a time. Another syntax for use within HTML is to use the attribute rel="tag" to indicate that the linked-to page acts as a tag for the current context. For example, to tag this page with 'folksonomy' you would add <a href="http://en.wikipedia.org/wiki/folksonomy" rel="tag">folksonomy</a>. More detail is available in the rel tag specification.

[edit]

Example websites that use Tags

Del.icio.us - A social bookmarking site that allows users to bookmark many sites and then tag them with many descriptive words, allowing other people to search by those terms to find pages that other people found useful.
Flickr - A service that allows users to tag images with many specific nouns, verbs, and adjectives that describe the picture. This is then searchable.
Gmail - A webmail site that was one of the first to allow categorization of objects using tags, known as "labels" on emails.
LibraryThing - A social book cataloguing and community website, tags feature heavily here.
Technorati - A weblog search engine.

semantic web

kleppten — Fri, 01 Sep 2006 07:22:41 CDT

The Semantic Web is a project that intends to create a universal medium for information exchange by putting documents with computer-processable meaning (semantics) on the World Wide Web. Currently under the direction of the Web's creator, Tim Berners-Lee of the World Wide Web Consortium, the Semantic Web extends the Web through the use of standards, markup languages and related processing tools.

[edit]

Relationship to the Hypertext Web

Currently, the World Wide Web is based primarily on documents written in HyperText Markup Language (HTML), a markup convention that is used for coding a body of text interspersed with multimedia objects such as images and interactive forms. HTML, as it is generally deployed, has limited ability to classify the blocks of text on a page, apart from the roles they play in a typical document's organization and in the desired visual layout. For example, with HTML and a tool to render it (perhaps Web browser software, perhaps another user agent), one can create and present a page that lists items for sale. The HTML of this catalog page can make simple, document-level assertions such as "this document's title is 'Widget Superstore'". But there is no capability within the HTML itself to unambiguously assert that, say, item number X586172 is an Acme Gizmo with a retail price of €199, or that it is a consumer product. Rather, HTML can only say that the span of text "X586172" is something that should be positioned near "Acme Gizmo" and "€199", etc. There is no way to say "this is a catalog" or even to establish that "Acme Gizmo" is a kind of title or that "€199" is a price. There is also no way to express that these pieces of information are bound together in describing a discrete item, distinct from other items perhaps listed on the page. The Semantic Web addresses this shortcoming, using the descriptive technologies Resource Description Framework (RDF) and Web Ontology Language (OWL), and the data-centric, customizable Extensible Markup Language (XML). These technologies are combined in order to provide descriptions that supplement or replace the content of Web documents. Thus, content may manifest as descriptive data stored in Web-accessible databases, or as markup within documents (particularly, in Extensible HTML (XHTML) interspersed with XML, or, more often, purely in XML, with layout/rendering cues stored separately). The machine-readable descriptions enable content managers to add meaning to the content, thereby facilitating automated information gathering and research by computers.

[edit]

Components

The Semantic Web comprises the standards and tools of XML, XML Schema, RDF, RDF Schema and OWL. The OWL Web Ontology Language Overview describes the function and relationship of each of these components of the Semantic Web:

W3C Semantic Stack

XML provides a surface syntax for structured documents, but imposes no semantic constraints on the meaning of these documents.
XML Schema is a language for restricting the structure of XML documents.
RDF is a simple data model for referring to objects ("resources") and how they are related. An RDF-based model can be represented in XML syntax.
RDF Schema is a vocabulary for describing properties and classes of RDF resources, with a semantics for generalization-hierarchies of such properties and classes.
OWL adds more vocabulary for describing properties and classes: among others, relations between classes (e.g. disjointness), cardinality (e.g. "exactly one"), equality, richer typing of properties, characteristics of properties (e.g. symmetry), and enumerated classes.

The intent is to enhance the usability and usefulness of the Web and its interconnected resources through:

documents "marked up" with semantic information (an extension of the HTML <meta> tags used in today's Web pages to supply information for Web search engines using web crawlers). This could be machine-readable information about the human-readable content of the document (such as the creator, title, description, etc., of the document) or it could be purely metadata representing a set of facts (such as resources and services elsewhere in the site). (Note that anything that can be identified with a Uniform Resource Identifier (URI) can be described, so the semantic web can reason about people, places, ideas, cats, etc.)
common metadata vocabularies (ontologies) and maps between vocabularies that allow document creators to know how to mark up their documents so that agents can use the information in the supplied metadata (so that Author in the sense of 'the Author of the page' won't be confused with Author in the sense of a book that is the subject of a book review).
automated agents to perform tasks for users of the Semantic Web using this metadata
web-based services (often with agents of their own) to supply information specifically to agents (for example, a Trust service that an agent could ask if some online store has a history of poor service or spamming).

The primary facilitators of this technology are URIs (which identify resources) along with XML and namespaces. These, together with a bit of logic, form RDF, which can be used to say anything about anything. As well as RDF, many other technologies such as Topic Maps and pre-web artificial intelligence technologies are likely to contribute to the Semantic Web. A popular application of the Semantic Web is Friend of a Friend (or FoaF), which describes relationships among people and other agents in terms of RDF. An implementation of a Semantic Web Browser is the BigBlogZoo. Over 60,000 xml feeds have been categorised using the DMOZ schema and can be spidered. It is free. The commercial version, MediaMiner, allows you to mine these feeds for information. Another freely downloadable tool is the new plug-in to Firefox, Piggy Bank. Piggy Bank works by extracting or translating web scripts into RDF information and storing this information on the user’s computer. This information can then be retrieved independently of the original context and used in other contexts, for example by using Google Maps to display information. Piggy Bank works with a new service, Semantic Bank, which combines the idea of tagging information with the new web languages. Piggy Bank was developed by the Simile Project, which also provides RDFizers, tools that can be used to translate specific types of information, for example weather reports for US zip codes, into RDF. Efforts like these could ease a potentially troublesome transition between the web of today and its semantic successor. A Semantic Web is not Artificial Intelligence. The concept of machine-understandable documents does not imply some magical artificial intelligence which allows machines to comprehend human mumblings. It only indicates a machine's ability to solve a well-defined problem by performing well-defined operations on existing well-defined data. Instead of asking machines to understand people's language, it involves asking people to make the extra effort to create information comprehensible to a computer. Even though it is simple to define, RDF at the level with the power of a semantic web will be a complete language, capable of expressing paradoxes and tautologies, and in which it will be possible to phrase questions whose answers would to a machine require a search of the entire web and an unimaginable amount of time to resolve. Each mechanical RDF application will use a schema to restrict its use of RDF to a deliberately limited language. However, when links are made between the RDF webs, the result will be an expression of a huge amount of information. It is clear that because the Semantic Web must be able to include all kinds of data to represent the world, the language itself must be compeletely expressive. The semantic web is the next generation web containing action-able information i.e. information derived from data through a semantic theory so that it can be processed directly and indirectly by machines. A semantic web agent does not have artificial intelligence, it uses the structured sets of information and inference rules to understand the relationship between different data resources. To classify the data from multiple domains based on its properties and its relationship with other data, we need to use descriptive technologies e.g. RDF, RDFS, OWL, XML (these are officially recommended by W3C) to add meaning to the contents of web documents to facilitate automated information gathering and research by computers. RDF is an XML-based standard for describing resources that exist on the web. Resources on the web are identified by URIs, which uses a global naming convention. RDF statements describe a resource, the resource’s properties, and the values of those properties. RDF statements are often referred to as “triples” that consist of a subject, predicate, and object, which correspond to a resource (subject) a property (predicate), and a property value (object). RDFS is used to create vocabularies that describe groups of related RDF resources and the relationships between those resources. OWL defines the types of relationships that can be expressed in RDF using an XML vocabulary to indicate the hierarchies and relationships between different resources.

[edit]

Potential benefits of the Semantic Web

Humans are capable of using the Web to carry out tasks such as finding the Swedish word for "car," to reserve a library book, or to search for the cheapest DVD and buy it. However, a computer cannot accomplish the same tasks without human direction because web pages are designed to be read by people, not machines. The Semantic Web is a project aimed to make web pages understandable by computers, so that they can search websites and perform actions in a standardized way. The potential benefits are that computers can harness the enormous network of information and services on the Web. A computer could, for example, automatically find the nearest manicurist or book an appointment that fits a person's schedule. Currently there is much data on our computers which we cannot browse, or process by, for example, pulling into a spreadsheet, graphing it or joining it with other data. This includes personal data like calendars, playlists, GPS coordinates, and bank statements; enterprise product and workflow and resources; and public data such as weather, events and the properties of materials. A lot of the things that could be done with the Semantic Web could also be done without it, and indeed already are done in some cases, but the Semantic Web provides a standard which makes such services far easier to implement. Tim Berners-Lee originally expressed the vision of the semantic web as follows: I have a dream for the Web [in which computers] become capable of analyzing all the data on the Web – the content, links, and transactions between people and computers. A ‘Semantic Web’, which should make this possible, has yet to emerge, but when it does, the day-to-day mechanisms of trade, bureaucracy and our daily lives will be handled by machines talking to machines. The ‘intelligent agents’ people have touted for ages will finally materialize. (Berners-Lee, 1999)

[edit]

Potential threats and criticism of the Semantic Web

Enthusiasm about the Semantic Web could be tempered by concerns regarding censorship and privacy. For instance, text-analyzing techniques can now be easily bypassed by using other words, metaphors for instance, or by using images in place of words. An advanced implementation of the Semantic Web would make it a lot easier for governments to control the viewing and creation of online information as this information would be much easier for an automated content-blocking machine to understand. In addition, the issue has also been raised that with the use of FOAF files and Geolocation meta-data, there would be very little anonymity associated with the authorship of articles on things such as a personal blog. Another criticism of the Semantic Web is that it would be much more time-consuming to create and publish content as there would need to be two formats for one piece of data. One format would need to be specialized for human viewing and the other would have to be specialized for machines. With this being the case, it would be much less likely for companies to adopt these practices as it would only slow down their progress. However, many web applications in development are addressing this issue by creating a machine readable format upon the publishing of data or the request of a machine for such data. Yet another criticism stems from the fact that the Semantic Web is based on a traditional client-server architecture, which ultimately is not scalable. URIs within RDF are still machine-specific references, which calls the persistence of these documents into question. Many have pointed to MAYA's Information Commons as a more practical implementation of the basic RDF schema that is both distributed and ultimately scalable. An eternal concern of some critics is how to find a source of revenue to pay the bandwidth costs. Additionally, just because your computer can retrieve and analyze data, does not mean that you will have the time to consider the analysis.
