March, 2007 RCO LLC, Analytical department Analytical department Typical scheme of analytical department operations, scenario 1 Search engine RCO Fact Extractor Unstructured text Business report Forecasts Dossier

March, 2007 RCO LLC, Indexers Typical scheme of analytical department operations, scenario 2 Facts: Primary knowledge Business report Forecasts Dossier RCO Fact Extractor Unstructured text

March, 2007 RCO LLC, special entities (date, address, phone, monetary amount, credit card and account numbers, vehicle and passport numbers, different measures, …) proper named entities (persons, organizations, geography, goods, …) entities named by noun phrases relationships between entities events, facts and their participants topics of text on which the author’s attention was focused RCO information extraction key features

March, 2007 RCO LLC, Result of parsing sentence: On September 7th, 2006 John Smith accepted conditions of the contract with New Design Ltd. for reconstruction of his family castle. Semantic network: the RCO way to represent content of text

March, 2007 RCO LLC, Semantic templates: the RCO way to extract facts This template can extract ‘contract’ facts from different texts, e.g.: On September 7th, 2006 John Smith has accepted conditions of a long-term agreement with New Design Ltd. for reconstruction of his family castle. Result of ‘contract’ fact extraction: Signer1 = ‘John Smith’ Signer2 = ‘New Design’ Contract = ‘long-term agreement’ Subject = ‘reconstruction of family castle’ Event = ‘accept’ Date = ‘On September 7th, 2006’

March, 2007 RCO LLC, Events, facts, and related participants extracted from text Extracted information about facts “to have an agreement” Sentences from source that describe facts “to have an agreement” RCO Fact Extractor English: text analyzer for business intelligence

March, 2007 RCO LLC, Objects to be monitored: companies and persons Extracted event participant: companies which were bought by MDM financial group Sentences from source that describe extracted facts RCO Fact Extractor Russian: text analyzer for business intelligence

March, 2007 RCO LLC, RCO team has already developed text analyzers for English, Russian, and Ukrainian languages. RCO team has rich experience in tuning of linguistic algorithms for different languages. RCO team is always open for new business partners, new languages, and new challenges.
