12:08:42 <tobiaswunner> Yes.
12:09:09 <cimiano> good thx
12:09:10 <tobiaswunner> Goals of meata requirements
12:11:08 <tobiaswunner> 6 requirements http://www.w3.org/community/ontolex/wiki/Goals_and_Scope_of_Ontology-Lexica_Community_Group
12:11:43 <cimiano> Nicoleta> agrees with requirement
12:12:16 <tobiaswunner> nicoletta M3 requires discussion (contextual aspects of meaning)
12:12:44 <gaguado> gaguado has joined #ontolex
12:13:29 <tobiaswunner> cimiano > many aspects (pragmatic) cannot be expressed fully on ontological knowledge. semantic reference system should pick up the meaning.
12:13:44 <cimiano> aldo> semantics by reference can be confusing
12:14:38 <tobiaswunner> aldo > reference of uris to multiple uris. is the object a good representation of the meaning behind the lexical entry?
12:15:43 <tobiaswunner> cimiano > technical level to point to uri. specific choice of granularity for domain needs.
12:16:53 <tobiaswunner> cimiano > make deeper meaning distinctions for lexical entries when lexical entries might not represent that meaning?
12:18:33 <tobiaswunner> aldo > words do not need unique senses. 
12:18:55 <tobiaswunner> aldo > as in wordnet.
12:20:15 <tobiaswunner> cimiano > agrees in principal. interpret meaning of words in context of ontology. more than wordnet.
12:21:02 <tobiaswunner> aldo > issue between reference of words and meaning. clarify requirements.
12:21:36 <cimiano> We will have at most 9 minutes more of discussion on the goals.
12:21:54 <cimiano> Who wants to speak? Please use q+ do indicate your intend to contribute to the discussion ;-)
12:21:57 <tobiaswunner> paulb > ontology-lexicon interface with ontology in first place. enrich ontologies to use them in nlp tasks.
12:22:22 <tobiaswunner> paulb > connect the ontology with lexical information.
12:23:31 <tobiaswunner> cimiano > group seems to agree on most of the requirements. semantic by reference (R3) requirement needs more discussion
12:24:04 <starred> q+
12:26:36 <tobiaswunner> starred (armando stellato) > does a lexicon ontology meta model require a lexicon model? openess. many application should understand what the reference of a given lexicon is without understanding the lexicon. semantic reference inside a given lexicon (with or without synset).
12:26:51 <tobiaswunner> cimiano > lexicon ontology model includes a meta model
12:27:50 <tobiaswunner> cimiano > the goal is not only to develop a lexicon meta model but a lexicon meta model as part of an ontology (lexicon-ontology interface)
12:28:31 <tobiaswunner> starred > what is the lexicon not?
12:29:01 <cimiano> [take up] next agendum
12:29:18 <cimiano> next agendum
12:29:24 <cimiano> next agendum
12:29:31 <cimiano> q-
12:29:33 <tobiaswunner> Action: starred add to wiki what lexicon is not
12:29:52 <cimiano> q- starred
12:29:58 <cimiano> next agendum
12:30:08 <cimiano> close agendum
12:30:58 <tobiaswunner> Start requirements from the use case to scope work and take decisions to work on the model.
12:31:25 <tobiaswunner> cimiano > a lexicon model could include many things
12:31:47 <tobiaswunner> cimiano > idea of modules and around a core
12:32:30 <tobiaswunner> cimiano > with clear deadlines for methodology for each use case
12:32:55 <tobiaswunner> nicoleta > agrees and says goodbye
12:34:18 <tobiaswunner> cimiano > description and motivation for each use case. in a very concrete way using examples. as well as the type of knowledge.
12:34:48 <tobiaswunner> cimiano > proceeding in this way would be easy and could drive the development of the specification.
12:35:19 <tobiaswunner> starred > its fine
12:36:33 <tobiaswunner> cimiano > proposed tandems for each use case, which means two people each from different research institutes. to allow for different views/interests for a use case.
12:37:39 <tobiaswunner> cimiano > 1st use case: ontology-based information extraction; ontology lexicon gives information for extraction
12:37:42 <aldogangemi> aldogangemi has joined #ontolex
12:38:27 <tobiaswunner> cimiano > plan is to extend the use cases with ongoing telcos
12:38:32 <tobiaswunner> cimiano > on wiki
12:39:14 <tobiaswunner> cimiano > 2nd ontology question answering; translate knowledge in sparql queries 
12:39:46 <tobiaswunner> cimiano > 3rd natural language generation; going the other way from triples to text
12:40:28 <tobiaswunner> cimiano > 4th integrating and publishing of legacy data; proposes Aldo a second owner besides John. 
12:40:58 <tobiaswunner> aldogangemi > agrees
12:42:15 <tobiaswunner> cimiano > Other interests in this use case: Veronique Malaise, Armando Stellato
12:42:18 <aldogangemi> (wave) to Armando
12:43:30 <tobiaswunner> paulb > two level of use cases. for example ontology-based IE with the general use and use cases on domain level (biomedical, financial, etc.). specifics with background the people are working in.
12:43:53 <tobiaswunner> cimiano > great idea.
12:44:18 <tobiaswunner> cimiano > so far discussed more the general level of use cases
12:44:38 <tobiaswunner> cimiano > 5th translation
12:45:51 <tobiaswunner> emontiel > someone interested in multilingual aspects in joining this use case?
12:46:21 <starred> I'll be
12:47:00 <tobiaswunner> emontiel > rich linguistic descriptions can help/contribute to provide better translations
12:47:29 <tobiaswunner> john > is ontology machine translation different from 4
12:49:23 <tobiaswunner> paulb > yes, the first is use ontologies to translate labels vs. translate text using the ontology
12:49:46 <gaguadod> gaguadod has joined #ontolex
12:50:40 <tobiaswunner> cimiano > 6th use case: cross-lingual information extraction
12:51:36 <tobiaswunner> cimiano > Other interests: Maria Maleshkova  from Open University
12:52:28 <tobiaswunner> cimiano > 7th use case: concept and named entity tagging in text. Use ontology to represent the named entities.
12:52:56 <tobiaswunner> cimiano > should we take this on board?
12:53:46 <tobiaswunner> armando > use of term named entities can be controversal because it might not be named entity recognition
12:54:36 <tobiaswunner> john > semantic light annotation using entities in ontology
12:55:23 <tobiaswunner> armando > how can this be made on ontology side; standard offline annotations?
12:55:45 <tobiaswunner> john > include also extra syntactic information which can be helpful to identify entities
12:56:15 <tobiaswunner> cimiano > it cannot be forseen in which particular way applications will use the model
12:57:01 <tobiaswunner> cimiano > for languages like english morphology might not play a big role but for other languages like arabic. annotations is not the primarily mission.
12:57:17 <tobiaswunner> cimiano > maybe rename use case
12:57:41 <tobiaswunner> cimiano > 6th use case: support to automatic ontology mediation
12:59:02 <tobiaswunner> armando > problem statement: many algorithms or alignments have been proposed without considering the environment as in automatic or manual alignment. how to automate this? performance issues for instance when the ontologies are too large.
12:59:14 <tobiaswunner> armando > here meta properties can be helpful
12:59:57 <tobiaswunner> armando > for agents
13:01:05 <tobiaswunner> armando > for example in FAO work the agrovoc vocabulary used skos which did not have enough linguistic knowledge. lack of implementations.
13:01:22 <tobiaswunner> armando > knowing the model in advance is useful for the algorithm
13:03:44 <tobiaswunner> cimiano > useful for other use cases as well
13:04:23 <tobiaswunner> armando > trade off for each use case. how much to talk about use case and how much too talk about the model.
13:05:46 <tobiaswunner> cimiano > given a vocabulary for the ontology-lexicon model the algorithm aggregates the this information
13:06:13 <tobiaswunner> armando > half of the labels are english half not
13:06:55 <tobiaswunner> armando > ontology is linked to wordnet synsets. synsets can be used as "labels".
13:07:21 <tobiaswunner> armando > synsets as anchors more precise as words
13:08:05 <tobiaswunner> john > which lexical resource you link to seems not particular to lexical linked data but linked data in general. be careful on existing approaches on linked data to not duplicate them in this use case
13:08:51 <tobiaswunner> john > existing linking mechanisms mainly developed in linked data community
13:09:54 <tobiaswunner> armando > agree to check duplication in community
13:10:37 <tobiaswunner> armando > agree as in issue of alignment is broader than lexical linked data
13:11:34 <tobiaswunner> cimiano > a requirement to the model should be the possibility of linking concepts to synsets?
13:12:31 <tobiaswunner> ciminao > we presented use cases now
13:12:54 <tobiaswunner> cimiano > q1: Are there any use cases we did not mention?
13:13:05 <tobiaswunner> cimiano > q2: Any people we should still invite?
13:13:33 <tobiaswunner> cimiano > q3: Timeline?
13:14:56 <tobiaswunner> aldo > fact extraction in obie use case?
13:15:17 <tobiaswunner> aldo > two problems extraction of facts and resolving entities
13:15:57 <tobiaswunner> cimiano > part of the use case
13:16:54 <tobiaswunner> cimiano > also semantic tagging use case would contain the issue of resolving
13:17:37 <tobiaswunner> aldo > information extraction stuff could also be merged depending on purpose of use cases.
13:19:05 <tobiaswunner> helene > normalization of text data
13:19:33 <tobiaswunner> paulb > lexis-nexis use case about semantic tagging in law texts
13:19:59 <aldogangemi> i was saying that IE and NER use cases might be merged or not depending on the scope of the model(s) this CG wants to deliver
13:20:25 <tobiaswunner> thanks
13:20:51 <tobiaswunner> helene > use a lexicon to normalize linked data
13:21:41 <tobiaswunner> helene > annotate document by creating rdf based on meta data
13:21:59 <tobiaswunner> paul > tagging the document by meta data which then can be used for indexing
13:22:23 <tobiaswunner> cimiano > sounds like semantic tagging by using the tag to index the document. more interesting would be to have a domain
13:22:45 <tobiaswunner> paulb > nexis-lexis in law domain
13:23:01 <tobiaswunner> cimiano > helene do you want to add use case description?
13:23:12 <tobiaswunner> helene > yes
13:23:46 <tobiaswunner> Action: Helene Rabault to add semantic tagging in legal text use case description on wiki
13:24:38 <tobiaswunner> cimiano > good. as start to agree on most uses to get going.
13:24:58 <tobiaswunner> cimiano > any other people to invite?
13:26:31 <tobiaswunner> helene > Christophe Tricot ontology terminology society in france
13:30:07 <tobiaswunner> cimiano > agenda target: end of march specification of use cases
13:30:44 <tobiaswunner> cimiano > two more telcos to finalize the use cases, january 13th, february 3rd
13:33:18 <tobiaswunner> cimiano > best time proposals
13:33:32 <tobiaswunner> cimiano > 2pm or 3pm CET
13:35:22 <tobiaswunner> cimiano > thanks all for participating. have a good day.
