Entities and Relationships

FEBS Letters Structured Digital Abstracts - With FEBS Letters Editorial Ofﬁce in Heidelberg; and MINT database Rome - SDA [Gerstein et. al]: ‘machine-readable XML summary of pertinent facts’ - For each ppi paper: proteins, protein-protein interactions, methods: provided by author in XLS - Started April 9, 2008: in ScienceDirect links to MINT and Uniprot - Now 117 articles with SDA: http://www.febsletters.org/content/sda - Being used as Gold Standard for Biocreative Challenge II.5 http://www.biocreative.org/tasks/biocreative-ii5/biocreative-ii5-evaluation/

expression of GSG1 stimulates TPAP targeting to the ER, suggesting that interactions between the two proteins lead to the redistribution of TPAP from the cytosol to the ER. MINT-6168263: Gsg1 (uniprotkb:Q8R1W2), TPAP (uniprotkb:Q9WVP6) and Calmegin (uniprotkb:P52194) colocalize (MI:0403) by cosedimentation (MI:0027) MINT-6168204, MINT-6168178: Gsg1 (uniprotkb:Q8R1W2) and TPAP (uniprotkb:Q9WVP6) colocalize (MI:0403) by fluorescence microscopy (MI:0416) MINT-6167930: Gsg1 (uniprotkb:Q8R1W2) physically interacts (MI:

OKKAM Project FP7 - EU funded project, 13 partners, 2008 - 2010 - Main goal: create entity identiﬁer repository - Create entity-centric architecture: - create new entities + synonyms where needed - offer interface/link where not needed - contain resolver, matcher, repository - E.g. http://sig.ma - semantic mashup of entity properties

http://sig.ma/search?q=p53

OKKAM Entity-centric authoring tool Current: - Build MS Word plugin to ﬁnd proteins in FEBS articles (i.e., semi-automating FEBS SDA!) - Now: testing web server interface to Whatizit Next: link to Biocreative metaserver - Add: links to other entities via OKKAM server - Prototype now being tested with FEBS Ofﬁce Future: - Create unique Author ID, straddling proprietary (Scopus) and other (ResearcherID, OpenID) systems - Allow query and resolution of authors/papers within Word

OKKAM Entity Editor in MS Word

OKKAM plugin vs. UCSD group Plugin UCSD plugin Okkam plugin Works! Can be Prototype, starting to test with downloaded, open source FEBS authors etc. Offline: load ontologies Online: call out to web services locally (soon...) Identify classes of entities Identify specific entities (e.g., a (e.g., ‘inhibitor’) specific protein) Works with other version of Word Works with Word 2007 (on a PC!) Stores annotations as XML Store annotations as Word metadata - maintain comments - can generate report metadata in Word info pane of entitieslinked to identifiers Work well together!

Hypotheses and Evidence

Issue with Biocreative challenge: From one of the documents in the training set: - In Xenopus oocyte maturation, cytoplasmic polyadenylation mediated by cytoplasmic polyadenylation element binding protein (CPEB) induces the translation of maternal mRNA [5]. - In mouse testis, another novel member of the CPEB protein family (CPEB2) and a homolog of xGLD-2 (mGLD-2) have been identiﬁed [7] and [8] versus: - TPAP was present in GSG1 immunoprecipitates (Fig. 2B). The in vivo data suggest that TPAP–GSG1 interactions occur in mammalian cells. Issue 1: what is experimentally veriﬁed content? Issue 2: what is new?

Discourse analysis of biological text

Discourse analysis of biological text - How can we identify line of argumentation in biology text?
