LMF Topics

• is this LIRICS?
• what is LMF compliance? Some ideas about
  header
• and related standards UNICODE
• docking mechanism of components
• relation mechanism
• operation mechanism
• this is LIRICS for MPI and Sheffield primarily
• DCR Syntax API
• LMF API
• lexicon and component registries incl metadata

3
DCR API 1

• tools such as GATE, LEXUS, ANNEX, have to make
  use of
• the ISO DCR (and probably other
  ontologies/concept registries)
• so we need an API (that can also be re-used)
• API has to be delivered finally as a web-service
  including all aspects
• UDDI layer to search/browse for services
• WSDL layer to describe the interface (methods,
  )
• SOAP layer for message exchange
• SYNTAX ISO DCR was not set up as a service, but
  as a management
• tool for editing boards
• therefore a split in final API (the ideal) and
  first phase API
• in 1. phase no webservice, URL and details of
  services are known
• all what comes is a result of a smooth
  interaction with the LORIA folks

4
DCR API 2

• function List loadProfiles ()
• give me all profiles in DCR
• function List loadDataCategories (aProfile,
  aWorkingLanguage, aObjectLanguage)
• give me all datcats for a certain profile
  result is perhaps a structure
• function List searchDataCategories
  (aQueryString, aProfile, aWorkingLanguage,
• aObjectLanguage)
• search for a datcat by specifying some pattern
  mostly a name
• function DataCategory loadDataCategoryReduced
  (URID, aWorkingLanguage,
• aObjectLanguage)
• give me some info for a certain datcat (ID,
  definition, conceptual domain)
• function DataCategory loadDataCategory (URID, a
  WorkingLanguage,
• aObjectLanguage)
• give me all info for a certain datcat for
  specified languages
• function List loadAllTopBroaderGenericConcepts
  ()
• give me all top conceptual domains
• function List giveLinks (aDataCategory)
• give me additional information such as
  constraints (to be worked out!)

5
DCR API 3

• function DataCategory loadBroaderGenericConceptDa
  taCategory
• (aDataCategory/URID)
• give me a broader concept for a name or URID
• function List loadDataCategoriesUsingBroaderGener
  icConcept (aDataCategory)
• give me all datcats for a broader concept
• function Workspace openWorkspace (aUserName,
  aUserLogin)
• open a private workspace for a user
• function DataCategory AddDataCategoryToWorkspace
  (aWorkspace,
• aDataCategory, aStatus)
• add a datcat to a workspace
• login into the system
• synchronize with a given cash

6
LMF Registries General

• an LMF API makes only sense if you have a
  service
• a service makes only sense if you can serve
  something
• what can LMF services serve
• lexical schemas
• extensions i.e. ready-made components created by
  someone
• LMF compliant lexica created by someone
• other lexica related information
• so we need registration services
• MPI will start doing so since we need it now
• will set things up similar to IMDI
• all is open (registries and portal code)
• everyone can easily setup his/her own portal
• will and have to synch about various things
• perhaps people will like it

7
LMF Registries

• registries must give the following services
• register and store a lexical schema
• register and store a lexical component schema
• register (and store) a lexicon (storage can be
  everywhere)
• delete an entry
• modify an entry
• let the user browse or search for
  lexica metadata based
• let the user browse or search for
  schemas metadata based
• for metadata start we suggest the stuff that
  came out of the discussions in
• ISLE/MILE (see IMDI)

8
LMF API 1

• if we have found a lexicon what then
• services based on web-services
• UDDI level why not the ISLE/MILE stuff
• function LexicalDatabase createLexicalDatabase
  (Name)
• create a lexicon in a workspace
• function LexicalDatabase loadLexicalDatabase
  (URID)
• give me a certain lexicon (into workspace or
  local?)
• function LexicalDatabase loadLexicalDatabaseDetai
  l (URID, aStructure)
• give me a certain lexicon part (filtering into
  workspace or local?)
• function void storeLexicalDatabase
  (LexicalDatabase)
• store/upload a lexical database
• function LexicalEntry createLexicalEntry (URID,
  LexicalDatabase)
• create/add a lexical entry
• function LexicalEntry loadLexicalEntry (URID)
• upload a lexical entry
• function void storeLexicalEntry (URID,
  LexicalEntry)
• update a lexical entry

9
LMF API 2

• function List searchLexicalEntries (aQuery)
• search for lexical entries matching the string
  unstructured
• function List searchLinguisticInformationUnits
  (aQuery, aStructure)
• search for lexical entries matching the string
  on specific attributes
• returning substructures (filtering)
• In addition
• function LexicalDatabaseSchema loadSchema
  (URID)
• give me a schema for a specific lexicon
• function void store (LexicalDatabaseSchema)
• store and register a schema
• function GlobalInfo loadGlobalInfo (URID)
• give me the metadata/globalInfo for a lexicon
• function void storeGlobalInfo (GlobalInfo)
• store and register a lexicon with metadata
• function List searchLexicalDatabase (aQuery)
• search for lexica based on metadata

10
LMF API 3

• what about
• relations
• where to store relations need registry
  mechanism
• if there is one integrated domain of lexica
  relations can be registered under this common
  root
• Gil took UML UML has everything in it
• so also relations are in UML so why
  bother
• Peter where to register is the question
• these were just first ideas!!
• Monica/Thierry haben ein Tool fuer die
  Constraints gemacht

11
What else Relations

• actually component association is a relation of
  special type

bank
breite Sitzgelegenheit
something broad to sit on

• need various type of relations between
• attributes and units in value strings
• each relation can be associated with
• features, i.e. relations can be seen as
• components in its own

sitzgelegenheit
etwas um zu sitzen
something to sit on
schmal
gegenteil zu breit
contrary to broad
12
Relation Mechanism

• need a generalized relation mechanism (look in
  Parole lexica etc)
• prefer very simple graphics instead of UML
  hiding the essentials

• relation components are almost normal
  components,
• i.e.they can have components and datcats
• however they dont have a parent
• do we need the destinction between to and
  from
• in general relations??
• component reference is a special type of
  relation
• here we need to distinguish to and from
• added a few additional stuff in paper (direction)

13
What else conditions (operations)
just one example from DOBES
lexemtype
if lexemtype stem idiom lexical word
head
sense nr
outer-body-L
meaning
if lexemtype auxil inflect affix
etc etc
sense nr
meaning effect

• probably better examples around
• if value(X) then modify contraints(Y)
• etc

categorial effect
etc etc
14
Operation Mechanism

• well nothing special perhaps (operators as
  datcats see Gil)
• but need sequence of operations
• but we need to be able to add complex operations
  (code)
• then need an invocation and interfacing
  standard

15
LEXUS etc

• we need to go ahead since we have to deliver
  usable infrastructures
• so hope on critical comments and fast
  convergence ?
• relation mechanism is next on our action list
• LMF API relevant for us since we have to combine
  LEXUS and LAMUS
• LAMUS Language Archive Management and Upload
  System
• is ready and working for simple objects
  (annotated media, )
• but need to handle complex objects such as
  lexica
• metadata is done people can integrate and
  search for lexica
• registries for schemas and sub-schemas comes
  next as well

16
LEXUS state

• ISO DCR integrated Shoebox MDF as well, GOLD
  to come
• private and protected workspace is ready
• Shoebox/ CHAT filters ready, XML grabbing to
  come
• first cross lexicon search is ready
• working on private DCR (stripped but compliant
  Syntax)
• working on Concept Profiles (bottom up generated
  concept lists)
• working on tools to link bottom up stuff with
  ISO,
• working on easy mapping framework
• first interaction with corpora is ready
• first merging is integrated
• what else??

simple structure. Components and datacategories
can be identified using different icons. All may
be dynamically created or modified.

• Support for various types of relations
• Import of data from other sources
• Support for other Data Category Registries, e.g.
  GOLD
• Integration with MPI archive
• Integration with exploitation tools (ELAN, ANNEX)
  
• Miscellaneous user requests
