ClioWire

Presentation

ClioWire is the platform developed by the EPFL Digital Humanities master students and the members of the EPFL Digital Humanities Lab (DHLAB). The platform is an hybridation between Twitter and Wikipedia. The ambition of this platform is to curate simple open bricks for historical knowledge, shaped as short texts. It is meant to be based on no prefixed ontology, but collectively negotiated conventions, reformatting by bots and visualization by dedicated apps. This is what works well on Wikipedia and in our Digital Humanities bachelor course. It is meant to offer easy onboarding, i.e. the process in which one get accustom to a new system/platform (even for beginners and people with only very basic IT skills). This is what works well on Twitter. One goal is to offer simple and robust long-term archiving for bricks of historical knowledge.

ClioWire curates Pulses as basic bricks for historical knowledge. They constitute some sort of minimal information unit coding relationship between entities and sources. They typically encode what is usually referred as events. Pulses are artificial construction that can be continuously being remolded and combined in order to create greater pieces of knowledge. We suggest to try to model our historical knowledge as an immense collection of Pulses.

ClioWire is constructed around the reintrepreation of two existing concepts : the concept of hashtag, the concept of bots, the concept of apps. The hashtage is much more than a convienent way for tagging content, it is a fundamental mechanism for coordinating semantics in extremely large distributed systems. Bot are much more than just funny users posting strange things on Twitter or helpers for Wikipedia, they are a new way of conceiving software engineering for large-scale projects. Apps are not just front end on mastered back-end, they can also be operates as interactive tools on data they are not mastering. The combinaition of these three concepts create a novel technological ecosystem for knowledge management and production.

Cliowire is constructed around the ideas of smooth semantization in contrast with right and formal models which in practive have difficulties to be adopted in large distributed systems.

Main characteristics

Their main characteristics are the following

• Pulses are 140-character long textual sequence (like tweets) (this constraint may be dropped)
• Syntax of Pulses follows some (evolving) conventions but no strict rules (like tweets)
• Pulses can be written by humans or by machine, and read by humans or machines (like tweets).
• Pulses have a first author but can be modified and rewritten by anyone. They are fundamentally considered as a common good (unlike tweets)
• Sequences of pulses are fully versioned. The history of their modification can be visualized (unlike tweets)
• Pulses can be attached to geographical coordinates, temporal coordinates, sources (URLs), document segments
• Each Pulses as a unique universal ID (like tweet), that can serve as reference in other Pulses and on the web.
• Pulses can be tagged as dubious or any other classification characterizing the trust one can have. The tagging itself can be partly done by bot (like for tweets)
• In sum, tweets are particular kind of Pulses, but Pulses are more general than tweets

The managing system for Pulses enables to do the following operations

• Inserting massive numbers of Pulses based on existing sources. If a bot imports Pulses massively, it will be their first author.
• More generally applying bot operation at a massive scale on Pulses (like for Wikipedia)
• Retrieving all the Pulses mentioning an entity (people, place) and visualizing them as timelines or maps or both.
• Retrieving all the intervention of a given user (i.e creation or editing of Pulses)
• Retrieving all the Pulses mentioning a given source (URL)
• Visualizing the editing history a sequence of Pulses
• Mapping the worldwide activity of Pulses
• Computing the list of the most active user, the most edited Pulses (like in Wikipedia)
• More things in the same spirit …

Rigid semantization vs smooth semantization

Contrastring the pro and cons of two approaches to the semantization process.

The hastag is a pivotal symbol

Origins

The US pound sign, number sign or hash symbol "#" is often used in information technology to highlight a special meaning The hashtag may contain letters, digits, and underscores.

1970: The number sign was used to denote immediate address mode in the assembly language of the PDP-11.

1978 : Brian Kernighan and Dennis Ritchie used # in the C programming language for special keywords that had to be processed first by the C preprocessor

https://en.wikipedia.org/wiki/The_C_Programming_Language

1986 SGML standard, ISO 8879:1986 (q.v.), # is a reserved name indicator (rni) which precedes keyword syntactic literals, --e.g., the primitive content token #PCDATA, used for parsed character data.

1988: The pound sign was adopted for use within IRC networks circa 1988 to label groups and topics

Pragmatics of the hashtag in social media

The Hastag use on Twitter was introduced in 2007, inspired by the IRC practice of channels

No one owns or administers a tag channel. A channel is created the first time someone posts a status with a channel tag. http://factoryjoe.com/blog/2007/08/25/groups-for-twitter-or-a-proposal-for-twitter-tag-channels/

Enough people started using them eventually that in 2009 Twitter decided to embrace them.

The hashtag "was created organically by Twitter users as a way to categorize messages."

"Twitter facilities one-to-many, asynchronous communication, and so tweeters are unlikely to be able to assume that they share contextual assumptions with all or any of their audience. By allowing tweeters to make their intended contextual assumptions accessible to a wide range of readers, hashtags facilitate the use of an informal, casual style, even in the unpredictable and largely anonymous discourse context of Twitter."

"The length restriction and the need to abbreviate and omit elements of the messages mean that the tweeter has to depend on her readers to be able to reconstruct the full intended message from the non-standard, abbreviated forms."

Tweeters are, therefore, writing for an “imagined audience” (Marwick and boyd, 2010; Brake, 2012; Litt, 2012).

as boyd (2010:46) notes, the discourse context does not persist, and “what sticks around may lose its essence when consumed outside of the context in which it was created”.

From The pragmatics of hashtags: Inference and conversational style on Twitter / http://www.sciencedirect.com/science/article/pii/S037821661500096X

When Instagram launched in 2010, the hashtag became the lingua franca for labeling content on both platforms.

"In 2010 there was the Arab Spring and the European anti-austerity movement, which both used hashtags to brand what they were doing. In 2011 unions and anarchists and the group Adbusters, of course, very famously started organizing and used the Occupy Wall Street hashtag. It became very useful in terms of just-in-time information about protest activity."

The hashtag was not created for Twitter. The hashtag was created for the internet.

Because of its widespread use, hashtag was added to the Oxford English Dictionary in June 2014 https://www.theregister.co.uk/2014/06/13/hashtag_added_to_the_oed/

Hashtag, from lingua franca to universal language

Hashtag is a way of indicating that a word is part of universal language

No body own hashtags. Goods and bad.

Examples of negotiated conventions and bot usage

Below is the results of a small scaled negotiation between the first 8 cliowire developers.

Coding Pulses

Someone may simply write in natural language, without any source or conventional naming

• Francesco Raspi lived on the Rialto Bridge.

However, this Pulse may being tagged as unreliable. It is better to automatically produce a Pulse.

• Francesco Raspi is the owner of parcels 514 in the Napoleonic Cadaster of 1808.

In order to increase possible articulatation between Pulses, hashtags can be used. Like for Twitter, there are no predefined hashtags but communities can negociate common ways to articulate the content of pulses. A community may decide to use very generic hashtag in order to increase the potential for generic processing. The list below reflects the current practice and on-going negociation in the community.

Entities

Each entities (Place, people, book, segment, volume, etc) is associated with a unique hastag.

Example: #MarinoZorzi is an entiy

Predicate #Eq

Predicate #Eq defines the commutative equivalence between two entities. This means that one can be replaced by another. It can be used to disambiguate mentions.

Syntax: (Entity or URL) #Eq (Entity or URL)

• Ex: #MarinoZorzi #Eq #MarinoZorzi34
• Ex: #MarinoZorzi #Eq http://..

Predicate #In

Predicate #In defines that one entity is a subpart / is included in another

Syntax: #In Entity Entity

• Ex: #Venice #In #Italy
• Ex: #PietyandPatronage_p3 #In #PietyandPatronage
• Ex: #YoungFilmmakers #In #Filmmaker
• Ex: #T_FrenchRevolution #In #T_XVIIIcentury

The syntax entity #In entity is for the moment prefered to the syntax #In entity entity, but this is subject to negotiation.

Predicate #Mention

The Hashtag #Mention is used to indicate the presence of an entity in a document. In transcription processes the resulting transcription is created as an entity . This entity will be disambiguate later on by the #Eq hashtag.

Syntax: #Mention #Entity #In #Volume #Source URL (opt #Prob_score)

• Ex: #Mention #Francesco_554eacdd_6734_4c91_9b9a_5e40869403e7_000490_942_5513_363_139 #In #554eacdd_6734_4c91_9b9a_5e40869403e7 #Source https://images.center/iiif/554eacdd-6734-4c91-9b9a-5e40869403e7-000490/942,5513,363,139/full/0/default.jpg

* Ex: #Mention entity entiy entiy #In Volume

Predicate #Tag

Syntax:

• Ex: #Tag #JeanLouisNicollier #realisateur #T_1998 URL

Predicate #Copresence

Syntax: #Copresence #entity #entity #In #volume/#entity

• Ex: #Copresence #FrancescoRaspi #BaptistaNanni #In #PietyandPatronage_p3

Copresence could be replace by the general syntax of #Mention with several entities.

Predicate #Creator

Syntax: #Creator #entity #entity

• Ex: #Creator #PietyandPatronage #WannaGoffen

Temporal Entity #T_

• Ex: #T_1998
• Ex: #T_1998_2000
• Ex: #T_FirstCentury
• Ex: #T_FrenchRevolution

Condition #When

• Ex: #AdamSmith #In #Economists #When #T_1753

Condition #Where

• Ex: #AdamSmith #In #Economists #Where #London

Condition #Source

• Ex: #AdamSmith #In #Economists #Source #p14_LeTemps

Coding knowledge

Pulses can also be used to code knowledge ungrounded in Space and Time like:

• Francesco Raspi is the son of Domenico Raspi

Or better:

• SonOf #FrancescoRaspi #DomenicoRaspi in http://…

Attributing ID

Pulses can be used to document segment, artwork images and other entities that do not typically receive conventional name can receive a unique Id (possibly generated automatically). This tends to be done using the #eq predicate.

• #ImprintingCini434 #eq http://…

Coding inferred facts

Pulses can be used to code inferred fact like

• Francesco Raspi is the grandson of Giovanni Raspi (inferred base on Pulse1, Pulse2 and Pulse3 and Rule3)

Encoding Rules

Inferring rules may also be coded with Pulses (using convention of variables)

• R: If ($A is the son of $B) and ($B is the son of $C$) then ($A is the grandson of $C)
