Document Annotation • Annotation can be seen as simply information about the document, assigned by a process or human, after the original creation of the document (Ogilvie, 2010) Transition from Observation to Knowledge to Intelligence TOKI2014
Some Applications of Document Annotation • AMIE- Annotation Model for Information Exchange – (Robert and David, 2006) • The model was reported to have been conceived with the objective of information sharing and reuse • The use of annotation process as an indexing approach that allows the users to identify and regroup documents or their sub-elements under a particular use context was employed in Maghreb and David (2008) • AMTEA -Annotation Model and Tools for Economic Actors– (Okunoye et al. (2010) • proposed the use of annotation representation as Attribute-Value-Pair (AVP) as a medium of capturing EI actors’ interpretation to document of interest. Transition from Observation to Knowledge to Intelligence TOKI2014
Problem Statement All search activities for information is associated with a decision problem. • Existing techniques for integrating context into document index are based on inference methods using statistical or linguistic methods. • These methods cannot capture the usage of information by the end-user. Transition from Observation to Knowledge to Intelligence TOKI2014
Document Usage Model • The document usage is modelled as a function of the following attributes: • DU = f(U, P, D, R) where: DU = Document usage U = User P = decision Problem D = Document representation R = document degree of relevance to the resolution of decision problem Transition from Observation to Knowledge to Intelligence TOKI2014
Document Usage Model The User attribute (U) is composed of the following values: U = {id, status, estab} where: id = a unique identity allocated to the user during the course of registering to use the system status = the current position of the user in the establishment or organization. estab = the users’ establishment information such as type of establishment (private or public) and name of the establishment. Transition from Observation to Knowledge to Intelligence TOKI2014
Document Usage Model Taking cue from Bouaka (2004), we describe the decision problem P as: P = {Obj, Signal, Hyp} where: Obj = the stake object attribute. Signal = the stake signal i.e. the level of the user’s knowledge about the decision problem. Hyp = the stake hypothesis i.e. what the establishment stand to gain or lose. Transition from Observation to Knowledge to Intelligence TOKI2014
Document Usage Model The attribute D of the DU is also formally define as: D = {id, title, abs} where: id = the unique identity of the document. This is automatically assigned by the system. title = title of the document abs = document abstract or summary. Transition from Observation to Knowledge to Intelligence TOKI2014
Document Usage Model The attribute R of the DU is document’s degree of relevance to the resolution of the decision problem. It s a function of the following attributes: R = f(UR, UY, NP) where: UR = User’s rating of document’s relevance to decision problem UY = User’s number of years in the establishment NP = Number of similar problems handled in the past Transition from Observation to Knowledge to Intelligence TOKI2014
Document Usage Model where is the users of the system is the document’s degree of relevance to decision problem (DP) is the terms from the DP description is the terms from the documents is the number of users in the system is the number of terms in the document space Transition from Observation to Knowledge to Intelligence TOKI2014
Document Usage Model • Items and are used to generate value added information • Items and are used to generate the usage index (UI). Transition from Observation to Knowledge to Intelligence TOKI2014
Model Evaluation • Vector Space Model was used to represent the document collection in the document space • Calculate the similarity between Decision Problem and key-term based document index • Calculate the similarity between decision problem and usage based document index • Compare the two results Transition from Observation to Knowledge to Intelligence TOKI2014
Calculating the Similarity between Decision Problem and Documents where: j = 1 …….. n (n= number of document in the document collection space). t = the number of terms in the vector space. dj = jth document vector in the document space P = decision problem transform to document vector in the document collection space wij = the weight of term i in document j. wi,q= the weight of term i in the query q (i.e. the decision problem).

Result Analysis • Threshold is usually set (e.g. 0.3) for documents to be considered relevant to queries. • Documents d4 and d5 will not be considered relevant to the query Transition from Observation to Knowledge to Intelligence TOKI2014
Conclusion • The IR component of the CI process is very crucial to speedy and easy resolution of DPs. • This work sought to keep track of what documents have been used for and incorporate it into the document representation scheme to enhance the quality of IR stage of the CI process. • The document usage model presented is used to preserve the effort, the decision makers put to discover relevant documents for the resolution of DPs Transition from Observation to Knowledge to Intelligence TOKI2014

Research Questions • Is it possible to model document usage computationally? • Can the document usage model be incorporated into document representation for modern information retrieval system (IRS)? • Can documents usage model enhance accessibility to documents required for the resolution of decision problem? Transition from Observation to Knowledge to Intelligence TOKI2014
Research Theory and Philosophy • The Philosophy of this work is derived from the gratification theory (Fiske, 1990) • Given the history of the usage of a document in addition to author’s defined key terms, there is the likelihood to increase the rate of accessibility to the documents in the nearest future. Transition from Observation to Knowledge to Intelligence TOKI2014
Research Aim • The aim of this work is to create a computing environment in term of software that will allow for creation and exploration of document usage Transition from Observation to Knowledge to Intelligence TOKI2014
Research Justification • Representing document with terms generated from the document itself and previous usage will enhance the rate of accessibility to the document • Thereby reducing the amount of effort that would be required by users to identify documents that are relevant to their information needs Transition from Observation to Knowledge to Intelligence TOKI2014
Research Objectives The specific objectives are to: i. formulate a model that augments document index with usage ii. design a system based on the model formulated in (i) iii. implement the system designed in (ii) and iv. evaluate the system Transition from Observation to Knowledge to Intelligence TOKI2014
Literature Review • Indexing by latent semantic analysis (Deerwesteret al. 1990) involves the use of Singular Value Decomposition (SVD) to analyse the term-document matrix. Modeling the underlying term-to-document association patterns is the key in this approach • Context Based Indexing in Search Engines using Ontology (Gupta and Sharma, 2010) involves the use of context repository, thesaurus and ontology repository to build the document index Transition from Observation to Knowledge to Intelligence TOKI2014
Literature Review • Okunoye and Uwadia(2011) Designed and Developed a Model for Generating and Exploiting Annotation in the Context of Economic Intelligence Proposed representation of annotation as attribute value pair rather than as atomic object, to allow the user to carry out annotation on documents with their specified attribute and value. Other related works are here Transition from Observation to Knowledge to Intelligence TOKI2014
Research Methodology • Document usage model was created with the use of Attribute Value Pair technique of document annotation and Vector Space Model of Information Retrieval • A system that integrates document usage with document index based on (i) was produced with the use of Unified Modelling Language (UML 2.0) • The prototype of the system was implemented with the use of PhPand MySqltechnology • The system was evaluated with the use similarity measure (i.e. Euclidean distance) between sample decision problems and documents • Form A Transition from Observation to Knowledge to Intelligence TOKI2014

Statement of the Problem • The process of identifying useful documents that contribute to the resolution of decision problems are often time-consuming and uneconomical. • Existing search systems do not incorporate document usage into document indexing. • To enhance accessibility to documents, there is the need for a system to augment document index with document usage. Hence, this study. • Back Transition from Observation to Knowledge to Intelligence TOKI2014
Research Methodology • Attribute Value Pair, a document annotation technique will be used to formulate a model that augments document index with document usage. A software system will be designed based on the model formulated with the use of Unified Modelling Language (UML 2.0). The prototype of the system designed will be implemented with PhP and MySQL technology. To evaluate the performance of the system, data on document usage will be collected through questionnaire administration and guided interview. The data will be collected from twenty (20) selected postgraduate students (M.Sc. and Ph.D.) in various departments in the faculty of Technology who are at different stages of their thesis. Similarity measure based on Euclidean distance between identified relevant documents by the respondents and their decision problems (i.e. research problems) will be used to evaluate the system. • Back Transition from Observation to Knowledge to Intelligence TOKI2014
