CfP: Entity Extraction and Linking Challenge (#Microposts2014 @ WWW2014)
=== Entity Extraction and Linking Challenge at the 4th Making Sense of Microposts Workshop (#Microposts2014) @ WWW 2014 http://www.scc.lancs.ac.uk/microposts2014/challenge/index.html 7 April 2014, Seoul, Republic of Korea === Microposts are a highly popular medium to share facts, opinions or emotions. They are an invaluable wealth of data, ready to be mined for training predictive modelings. This year the #Microposts 2014 Workshop will host an Entity Extraction and Linking Challenge. The overall task of the challenge is to automatically extract entities from English microposts, and link them to the corresponding English DBpedia v3.9 resources (if the linkage exists). As linking stage we aim to to disambiguate expressions that are formed by discrete (and typically short) sequences of words. Existing entity linking tools are intended for use over news corpora and similar document-based corpora with relatively long length. We organise this challenge to foster research into novel, more accurate solutions for the automatic entity linking in (much shorter) micropost data. We will ask the participants to automatically extract entities (e.g., Obama, London, Rakuten) belonging to all entity types (e.g., Person, Location, Organisation) from a collection of microposts. Participants will have to automatically provide context-relevant DBpedia resources for each entity in a micropost. DATASET --- The dataset comprises of 3.5K tweets extracted from a much larger collection of over 18 million tweets. This collection, provided by the Redites project (http://demeter.inf.ed.ac.uk/redites/), covers event-annotated tweets collected for the period of 15th July 2011 to 15th August 2011 (31 days). It extends over multiple noteworthy events including the death of Amy Winhehouse, the London Riots and the Oslo bombing. Since the task of this challenge is to automatically extract and link entities, we have built our dataset considering both event and non-event tweets. While event tweets are more likely to contain entities, non-event tweets enable us to evaluate the performance of the system in avoiding false positives in the entity extraction phase. The dataset has been split into a training (70%) and testing (30%) sets. Following the Twitter TOS we will only provide tweet IDs and annotations for the training set; and tweet IDs for the test set. We will also provide a common framework to mine these datasets from Twitter. The training set will be released as tsv file where each line consists of : - tweet_id - entity_mention_1 - entity_uri_1 … - entity_mention_n - entity_uri_n Tokens are separated by TABs. Entity mentions and uris are listed according to their appearance order in the tweet. We will timely advertise the release of the data sets on the workshop mailing list. Please subscribe to https://groups.google.com/d/forum/microposts2014. More information about dates are available in the Challenge website. EVALUATION -- The evaluation consists of two separated stages: 1.- Paper peer review : A community of experts of the domain will judge the quality and applicability of the approaches taken, to provide useful insights on your research; 2.- Precision and Recall: F1 (F-measure with beta = 1) will be computed on a gold standard manually created from the test set. The automatically extracted entities and links will be both matched against this ground truth. All submissions will be only ranked according to the F1 of each best submission. SUBMISSIONS --- Submissions should be provided as a zip file using your system name as the file name (e.g. 'awesome.zip'), containing: 1. a TSV file with your system name (e.g. 'awesome.tsv'). We accept up to 3 different submissions, and we will consider *only* the best. If you do so you must specify clearly in your paper the modifications applied to each labelled submission. In this case the submission should contain each of up to 3 TSV files with the tool/system name with _n appended to each (e.g. awesome_1.tsv, awesome_2.tsv, awesome_3 ). In order to evaluate your submissions we require you to submit a tsv file following the format in which the training set is provided. 2. a paper of 6 pages describing your approach and how you tuned/tested it using the training split. All submissions must be in English. Submissions must be in PDF formatted in the style of the Springer Publications format for Lecture Notes in Computer Science (LNCS) [http://www.springer.com/computer/lncs?SGWID=0-164-6-793341-0]. For details on the LNCS style, see Springer’s Author Instructions. All submissions are not anonymous. Please send us your submission before the deadline through Easychair

Uncertainty and Imprecision on the Web of Data
July 15-19, 2014
Montpellier, France
--
Special Session
*at the*
15th International Conference on Information Processing and Management of
Uncertainty in Knowledge-Based Systems
http://www.ipmu2014.univ-montp2.fr
Submission deadline December 31, 2013

***Short description***
Phenomena related to uncertainty and imprecision are common on the Web of
Data. On the one hand, data published as linked open data are often
incomplete and of variable quality; we are frequently faced to dealing with
missing, imperfect, vague and imprecise data in many real-world
applications. On the other hand, often these data's meta-models are of
inherently uncertain or imprecise nature and dealing with these resources
requires a suitable framework. Although active research addressing these
issues has been conducted recently, handling uncertainty and imprecision is
still an open problem in the context of the Web of Data.
The goal of this special session is to bring together researchers working
in the field of imprecise/uncertain knowledge and data management and
interested in linked open data technologies. The session will address
problems related to handling imprecision and/or uncertainty of data and
ontologies in the processes of publishing, interconnecting and querying
data by following the Linked Data principles. Two major (partly
intersecting) communities are targeted: (1) the community dealing with
reasoning under uncertainty and (2) the community focusing on knowledge
discovery, data mining, data integration and information retrieval when
data are fuzzy, imperfect or imprecise.
The topics of interest can be articulated along the following axes (the
list being non-exhaustive):
* Fuzzy ontological languages
* Linking of imperfect/imprecise/vague data
* Representaion of uncertain links
* Fuzzy/probabilistic/approximate ontology matching
* Reasoning techniques under uncertainty and fuzziness
* Imprecision and uncertainty in specific domains, e.g.:
- the biological and bio-medical domains
- the geo-spatial domain
- trust, provenance and security
- multimedia
- multilingualism
* Quality of open data
* Fuzzy data mining and knowledge extraction
* Querying warehouses opened on the web: imprecise queries and approximate
answers
***Submissions***
Contributions to the special session can be made in terms of papers which
will undergo the standard reviewing process of the IPMU 2014 conference.
Complete information regarding the submission process can be found at the
conference website: http://www.ipmu2014.univ-montp2.fr, more precisely in
the section Program - Special Sessions. In the submission process, note
that the name of the special session will appear (and has to be selected)
in the list of conference tracks on the Easychair site. The accepted papers
will be published in the proceedings of IPMU 2014.

Re: [Final CfP]: Uncertainty and Imprecision on the Web of Data @ IPMU 2014
Hi Konstantin,
As an irony fan, I note that the conference on Uncertainty and Imprecision
begins the day after Bastille Day. Interesting comment on the revolutionary
character of the Web of Data :-)
Uncertainty and imprecision can not be solved by disapproval. If you took a
stack of 10 Trillion Dollar Bills (10^14) (representing Water Molecules) then a
Chemist would tell you that one bill in the pile has no picture of George
Washington and one bill has two pictures of George Washington. Quantum
Mechanics is weird and it makes Economist's heads blow up. Anyway ...
I doubt I would be able to attend but can offer some organized, if not exactly
structured (the American Public Domain is not structured, just free) data for
visualizations.
