1. From sentence to sense level information retrieval Bridging CONTENT and object with HOLTRAN Technology

2. Mission Statement HOLTRAN (Higher Order Logic Translation) Technology fills the gap between two fundamental methods of representation of information: unstructured texts and structured data. HOLTRAN Technology is aimed to serve as a universal international standard of representation, storing and exchange of information Our mission is to become an industry-leading provider of Natural Language Processing (NLP) solutions for consumers and companies HOLTRAN Technology Ltd.

3. What do we do? Next generation knowledge base engine Extracts information from multi-lingual natural language texts Stores the information in a structured form Keeps both semantic and textual information on equal rights Enables knowledge base queries in natural languages HOLTRAN Technology Ltd.

4. Why? The challenge … is to find effective solutions to unlock the value from unstructured information sources, and to leverage it in Business Intelligence deployments Butler Group Poor classification costs a 10,000 user organization $10M annually. Poor classification costs a 10,000 user organization $10M annually. Usability expert, Jacob Nielsen Unstructured information doubles in quantity every three months Gartner Group In modern enterprise, 85% of data is unstructured In modern enterprise, 85% of data is unstructured Butler Group

5. NEED common interface framework for diverse multilingual and multiform sources of information. OBSTACLE unstructured information human-friendly BUT meaningless to computers. and heavily dependant on manual processes HOLTRAN Technology Ltd.

6. The general need for… common interface being able to bind and put in order diverse multilingual and multiform sources of information …is also lately sharply realized by European leading companies and by ITEA board which has formulated in its Technology Roadmap on Software Intensive Systems the main challenge for Semantic data as the possibility for applications to understand the meaning of each others data and has invited HOLTRAN Technology Ltd, to the annual ITEA meeting in Amsterdam (January, 2003). As result, the company was invited to join the 6-th call EUREKA ITEA consortium: DigiNews (News and Information for mobile e-paper terminals. Leader: Philips Technology) HOLTRAN Technology addresses this need providing a framework for building semantic knowledge based information systems of a new generation being capable to extract semantic (structured) information from multilingual textual (unstructured) form and vice versa – to express the stored structured information in textual form.

7. Novelty Employment of a knowledge model based on our own improved Multiple sorted type theory. HOLTRAN based system is able to store arbitrary order relationships between semantic entities (also incomplete and contradictive information) store extendable language definitions of any type and complexity effectively evaluate full responses to any queries related to the stored information HOLTRAN Technology Ltd.

8. Novelty in Question Answering Unlike search engines, HOLTRAN Question Answering system aims to supply users with the essence of "just the right information," instead of merely providing a list of hits. Current question answering systems are based on sentence level information retrieval. The rate of correct answers in such systems is about 70%. HOLTRAN Question Answering system provides a revolutionary leap from sentence level retrieval to sense level information retrieval and answer formation

9. Why we are better than other QA systems? State-of-the-Art question answering systems use a variety of linguistic resources to understand users queries and match documents sections. Most common linguistic resources include: –part-of-speech tagging –parsing –named entity extraction –semantic relations –dictionaries, WordNet, etc. HOLTRAN Technology provides a unique framework embracing these resources inside the system and thus covering complex lexical, syntactic and semantic relationships between question and answer strings.

10. The social impact of HOLTRAN in 2020 will cover the following situations: Two or more people talking over the "phone" each in his native language and receiving the answer in it. Traveling in a car one can ask "it" any relevant question and receive the system response in his native language. One can receive ANY "newspaper" in his native language (the first step to be done through our participation in DigiNews ITEA project). Fully automated call centers: each user can be receive the answer in his native language. Translation form one artificial language to another providing full database compatibility without additional software development (solution of PDM-ERP compatibility problem). No manual transaction treatment: all e-mails read and treated automatically (Spam, as well).

11. Relational DBMS Unstructured documents System Server System Client Local documents User Meta data (SQL) Documents (text stream) Meta data (XML) Documents (text stream) Meta data + Documents (GUI) Typical modern information system architecture The system repository contains a relational database of some related meta information a hybrid of a vault of textual documents stored as unstructured "black boxes The System Server provides execution of queries to the relational DB and access to the textual documents. communicates to the system clients usually via GUI for the end users. HOLTRAN Technology Ltd.

12. The basic problems of classical architecture: Redundancy and inconsistency between contents of primary documents and meta information on these documents Limitations on inter-version and inter-application compatibility HOLTRAN technology solves these fundamental problems due to its ability to extract the semantic content from unstructured documents extract more semantic information from the same documents upon extending language definitions without a new software development express the content in a textual form. HOLTRAN Technology Ltd.

13. HOLTRAN KBMS HOLTRAN Interpreter Content + languages definitions (HOLTRAN native) Meta data + Documents (text stream) Local documents User Meta data + Documents (user native) Browser HOLTRAN based information system architecture HOLTRAN KB stores on equal rights both application information definitions of various external languages, i.e. any artificial or natural languages used to exchange information with applications and users. HOLTRAN interpreter translates information coming from users and documents in external languages to the internal KBMS language and vice versa. It allows users to communicate with the system in their native languages. HOLTRAN Technology Ltd.

14. How it works? Objects are assigned entity type e John plays table tennis well t stands for truth type Interior axiom representation HOLTRAN Technology Ltd.

15. How it works? (2) Querying in HOLTRAN: Who plays table tennis well ? Inference procedure consists in finding of all consistent substitutions of free variables (xs) in the tested formula with which it is provable. Interior axiom representation HOLTRAN Technology Ltd.

16. What is higher order logic? First Order Logic: Mary and Cathy play tennis. First order logic expressions – the ones being written in SQL and containing constants and variables only of simple types e, t,… Mary or Cathy Not Mary and Cathy First order part

17. What is higher order logic? (2) First Order Query - queries a variable of the first order: Who plays table tennis well ? Higher order logic expressions – the ones containing constants and variables of variable order types ee, et, eet … Second Order Query - queries a variable of the 2-d order: What does John do? How does Mary play tennis ? 4-th order query

18. How do we do it in HOLTRAN Native programming language HOLTRAN Native programming language is especially designed to express any human-percept notions and ideas, including definitions of natural languages This is how looks the piece of code in HOLTRAN Native to program the questions of the sort: How does Mary play tennis ? (("How does"=) ##& NounPhrase ##> VerbPhrase ##& ("?"=) =>> \np:e\vp:et((x:(et)et vp:et) np:e)) This is the way Interpreter translates from English to HOLTRAN Native and back to English: < How does Mary play tennis ? > Test (x:(et)et (_3:eet (COM _5:et)) (ID _2:e)); > Assert (_1:(et)et (_3:eet (COM _5:et)) (ID _2:e)); > Mary plays tennis well.
