METHOD FOR AUTOMATIC PROCESSING OF INFORMATION MATERIALS FOR PERSONIFIED USE

Abstract: Inventions relating to the field of information technologies provide an appropriate account of "user's profile", i.e. user's information need, and supply a user with data about the content of the whole complex of processed information materials in a integrated form with a quantitative evaluation of relative covering, in processed materials, various components of "user's profile" both separately and in relations thereof. The presence of data in materials being processed relating to elements of "user's profile" is detected and these data are demonstrated in visual or audiovisual forms local structures, i.e. graphs reflecting a character of relationship of each independent sense fragment of materials being processed with the mentioned elements, are generated. Some from the suggested methods provide a user with the statistics, in visual form, on the frequency of using of various particular local structures and structures with different number of elements of "user's profile" included therein. In other embodiments, an integrated graph presenting a logical sum of local structures is generated with demonstrating an image of this graph for a user, as a whole or by separate components. In all embodiments, the final result of the method directs a user on a priority selection of those parts of information materials which meet his information need in the most grade as well as helps to discover latent problems not appearing acquaintance with material 6 independent claims.

Description: The present invention relates to information technologies, particularly to processing information materials to prepare them for personified use that is to the processing oriented on a particular user or a group of users having definite, supposed as known, needs in information. There are wide known traditional methods for processing information which is contained in materials' flow to prepare thereof for using by definite customers including methods for producing abstracts and summaries as secondary materials which characterize or present shortly contents of primary materials. Such methods not suggesting any formalized principals for evaluating the content of primary materials have drawbacks due to human factor in individual approaches of specialists affecting on the processing and correspondingly on results. There are also known methods for processing information in materials' flow by listing preselected hint words and producing an abstract of the document by juxtaposing extracted sentences containing such words. (See as an example European Patent application 0 361464 A2 with date of publication 04.04.90.) In similar methods there is more probable, than in the methods of the previous group, the selection of only that information which is connected with the information needs of the user defined by a list of reserved words. However, missings of wanted information and false hits are possible since words can have more than one meaning and the same meaning can be expressed by different wordings. An example of an information retrieval user interface is Hemmje M et al "Lyber World - A visualization user interface supporting fulltext information retrieval" SIGIR '94. Dubli, July 3-6, 1994, no. CONF. 17, 3 July 1994, pages 249-259, XP000475325 Croft W B, Van Rijsbergen C J (Editors). In this system visualisations are used to communicate information search and browsing activities in a natural way, applying metaphors of spatial navigation in abstract information spaces. Moreover, a number of methods is known which are grouped by directing on detecting a "latent structure" of information being interesting for the user on the base of an analysis of his previous demands. (See as an example Scott Deerwester et al., "Indexing by Latent Semantic Analysis", Journal of the America Society for Information Science, 41(6), p. 391-407, September 1990.) In these methods which are also oriented on detecting coincidences of search images with elements of the processed materials' content due to more complicated composing of the indicated images forming so called "user's profile", i.e. his information needs' characteristic, errors, inherent in methods of the previous group, are less probable. However, in this and similar methods, the stress is made on forming "user's profile" making this in advance and not paying attention to obtaining an integrated presentation of the processed materials' content as well as to the content of one multiaspect document of great volume during processing itself since such methods including methods of the previous group are oriented on an independent analysis of separate materials of the processed flow. Moreover, although the noted stress creates some background for automation of such methods it is not favourable for full activating abilities of specialists dealing with "hand" processing the flow of information materials. The invention sets out to obviate or mitigate the above described problems. Accordingly a first aspect of the invention provides a method for automated processing information materials according to Claim 1. Preferred features of this aspect of the invention are set out in Claims 2 to 5. A second aspect of the invention provides an apparatus consisting of a suitably programmed computer system for automated processing of information materials as set out in Claim 6. Preferred features of this aspect of the invention are set out in Claims 7 to 10. Embodiments of the invention will be described by way of example and with reference to the accompanying drawings in which:- Fig. 1 is a block diagram of the automated technology for processing of information materials for the personified use; Fig. 2 illustrates technical means for automated processing of information materials according to embodiments of the invention; Fig. 3 is a diagrammatic illustration of generation of an image of a local structure being prescribed to a fragment of the information materials; Fig. 4 are examples of local structures having nodes which correspond to dominating elements of the characteristic of "user's profile" and to fully connected local structure; Fig. 5 is an example of generating an integrated graph for the totality of local structures of Fig. 4; Fig. 6 is an example of a set of local structures; Fig. 7 is an example of structures which can be included in the set additionally; Fig. 8 is a totality of local structures generated under processing particular information materials; Fig. 9 is an integrated graph corresponding to the totality of local structures of Fig. 8; and Fig. 10 is an example of a component of the integrated graph of Fig. 9. The information technology based on any of the embodiments including the use of results thereof and previous preparative operations is shown in Fig. 1. The preparative operations include the generating of "user's profile", the selecting of information materials and the fragmenting thereof. The embodiments, as they are, include the indexing of information materials as well as the representation of obtained results. Actions on the use of obtained results include the interpreting thereof. The embodiments of the invention do not demand special forms of information materials and carriers thereof. The methods permit the use of any documentation materials. These materials can include text materials, videomaterials and others. "User's profile" is an aggregate of sense elements characterizing the user's information need. Depending on information need, these elements can include concepts, definitions, problems, tasks, indexes, objects or, as general case, terms (words or word combinations) or term combinations (sentence or several sentences). When determining "user's profile", relations between elements thereof are not being set. Various known methods for generating "user's profile" are discussed for example by Allen (Allen, R. User models: theory, method and practice international. Journal of Man-Machine Studies, 32 (1990), pp. 511-543). In the use of the embodiments of the invention, it is essential that elements must be approximately of one level of importance from a view of user's interest and have an equal nature (be near one to another in designation, type). Elements of "user's profile" can be represented not only in form of wordings but in form of visual images. The fragmenting information materials should be understood as separating them into separate semantic modules. For such a type of materials as messages, the fragmenting means the separating of significant messages and a fragment can be a message itself or a part thereof. For such a type as documents, a fragment can be in form of a paragraph. The indexing means the juxtaposition of the sense of "user's profile" and prescription thereto one or other elements. When indexing, it should be set to what definite type a character of relationship between elements juxtaposed therewith belongs and the type to be described by a graph - by a local structure. This is a hierarchy structure and can be either a structure represented by a full connected graph, as in the second and fifth embodiments, a structure from a number of structures of precomposed set thereof ("library" of structures) as in the third and sixth embodiments, or a structure of any form being set by a specialist performing the indexing as in the first and fourth embodiments. The selecting of one or another structure is defined by associations of a specialist making the indexing when comparing a sense of a fragment and a totality of elements of the characteristic of "user's profile". Dominating elements, the presence of which define the hierarchical nature of a local structure being selected, are defined by a sense of a fragment relative to the information need of the user as more important (having a priority) in comparison with others for this fragment. A local structure obtained from indexing is a totality of sense elements of "user's profile" and logical relations between them. An integrated graph should be understood as a logic sum of all local structures obtained during indexing. They are marked undirected connected graphs with the same multiplicity of edges. A logic sum of local structures is obtained by superimposing thereof with matching similar nodes (definite elements of the characteristic of "user's profile" are associated with nodes). The multiplicity of edges of an integrated graph is equal to a number of coincided relations between corresponding pairs of nodes in local structures being summated. Results of the processing of information materials are represented in form of text fragments, plots, diagrams, tables. The interpretation of results obtained after processing is the last stage of information technology performed by the embodiments. The interpretation detects, inter alia, complexes of closely-related elements defining "user's profile", single loosely-related elements or unrelated elements with others. The further qualitative and quantitative analyses permit to make conclusions about the correspondence of processed materials to the information need of the user and the information saturation of these materials from the view of the given "user's profile". Performing all the processing from a position of a given "user's profile" defines the technology being described as the technology of the processing of information, materials for the personified use. An approximate set of technical means for performing the suggested methods as shown by a diagram in Fig. 2 includes a computer monitor (or monitors) 1 with a keyboard 2 and a pointing device ("mouse") 3, a processor 4, a memory 5 of programs, intermediate and final results of processing, carriers 6, 7 of information materials' files being processed and elements of the characteristic of "user's profile". When using such a set of technical means on the stage of indexing, one display field of the monitor or one of the monitors, if there are several monitors, represents the content of primary materials separating each fragment by distinctive lighting which differs from neighbour lighting. It is possible to look through images corresponding to elements of "user's profile" in another display field or on another monitor at the mode of scrolling. In another one interactive display field or in the same field where elements of "user's profile" are represented or on a display of a separate monitor, images of radio buttons are lighted selecting which by means of a keyboard or by a graphics manipulator you can generate features of the presence of a sense relationship between a fragment being indexed and ones or other elements of "user's profile" being represented. In similar way local structures are represented and the selection of them is performed and a form of a structure is generated. The completing stages of the methods represent results of the statistic analysis of frequencies for using elements of the characteristic of "user's profile" being the dominating ones in local structures together with information about corresponding elements themselves and about those fragments of primary materials for which the presence of relationship of the content with corresponding elements of "user's profile" has been detected. The process of the indexing, i.e. generating an image of a local structure prescribed to a fragment of information materials, is shown in more details in Fig. 3 where a symbol "X" for a fragment of information material being processed and a symbol "Y i " for components of "user's profile" are used. The diagram in Fig. 3 is schematic in that it illustrates simultaneously three possible methods of the indexing used in the second and fifth embodiments (two low blocks on the left), in the third and sixth embodiments (two low blocks at the middle) and in the first and fourth embodiments (a lower block on the right) correspondingly. Forms of local structures used in the second and fifth embodiments are explained by Fig. 4 a,b,c which show a simplest hierarchical structure with dominating node Y 3 , a hierarchical structure with two nodes Y 6 and Y 3 at the high level and a full connected structure correspondingly. The generating of an integrated graph is explained by Fig. 5 on the base of particular graphs of local structures of Fig. 4 (multiplicities of edges) are shown by digits. Such a principal of generating an integrated graph is used in all the embodiments. An example of a collection ("library") from base local structures for use in the third and sixth embodiments is illustrated in Fig. 6 a-d which show correspondingly: a structure with a leader (a dominating element of "user's profile") which is similar to Fig. 3a and is applicable for any number of nodes Y i , nodes which are not leaders form an environment for a leader; a structure of ring type in which only neighbour nodes are linked in pairs being also applicable for any number of Y i is a structure with loosely-coupled interface; a regular structure in which all nodes are equal being applicable for a number of Y i multiple of 3 refers to structures with average coupling; a fully-coupled structure in which each Y i is coupled with others is a structure with closely-coupled interface. Additionally, structures of such types as shown in Fig. 7 a,b may be included in the collection. Fig. 7 shows a structure of "dumb-belis" type in which A and B are local structures from a number of base structures shown in Fig. 5. In a particular case, A and B can be the same structure. The presence of an edge connecting two base structures reflecting independent subject groups of notions is essential for this structure. An edge between A and B means the presence of relationship between any pair of notions one of which is included into A and another into B. A designates also one of base local structures in the structure of Fig. 7b. Edge "a" designates a relationship between Y i and any notion included in A. Moreover, the library may include types of local structures which are generated recursively when one from base local structures is a separate notion. In any of the embodiments a specialist performing the indexing can prescribe to a separate fragment being processed an arbitrary graph as a local structure, in particular such a graph which is generated from one of base structures by including or discluding separate edges. The fourth, fifth and sixth embodiments, on the designation thereof, can be compared with methods for producing abstracts which are applicable for the characteristic of information materials' content. Usual methods do not provide the generating of recommendations for the user about appropriate sequence of acquaintance with subjects in which the user is interested. The expediency, in this case should be understood as saving the time suggesting to the user not to acquaint with materials in series as hey appeared but at first with those materials which are the most corresponding to his interests. The utility relating to making abstracts (indexing) of a local structure has both the microeffect and the macroeffect. The microeffect is concluded in saving time simultaneously with obtaining more information by the user when seeing a separate local structure prescribed to some material on a display. In case of usual producing abstracts, the user must read words of an abstract sequently, a word by a word. In case of providing to the user an abstract in form of a local structure, the user catches all elements of this structure at once simultaneously with a character of relationship between them. There is no hard sequence of acquaintance. If there are many Y 3 , for example more than a hundred, the first word from Y for each node is lighted sequently on a display to accelerate the orientation of the user in a local structure, then 2 words and so on. Here, human psychophysical abilities to understand at once, that is to catch a type of a structure which being seen. The macroeffect is achieved when the user is provided with total information about all local structures by means of which abstracts of materials, interesting for the user, are made. The user is provided with the output of logical statistics on a frequency of use of separate notions or combinations thereof as a leader as well as combinations of Y i which were put into closely-coupled local structures (type 4). As the result, the user has chance to generate a strategy of acquaintance with materials based in whole on information which is output to him. Taking into consideration that data output to him are oriented on describing the most essential and important information, the user has chance to reduce time of acquaintance with materials in whole. As mentioned above, data which can be, represented as results being provided to the user are the same for all the embodiments. However, such results are intermediate in the first three methods but the main result for them is a result in form of information included in an integrated graph. In is essential for analyzing information included in an integrated graph to provide means for detecting and attracting the attention of the user to structure features of an integrated graph. Such features may include so called "logical bunches" of elements' combination of "user's profile" which are the most frequent in different local structures. For detecting them, the user is provided by output of elements' combination in "user's profile" ordered on a sum of relationships, accounting a multiplicity between elements included in a combination (back-end couplings), and a sum of relationships, accounting a multiplicity between included in a combination with all others (front-end couplings). The detected "bunches" may be interpreted as complexes of elements "containing the base content" of information materials as a new problem, not yet realized by the user, and having a relation to his information need. The use of the suggested methods as noted above, is performed in the interactive mode supposing the representation of current and summarized information represented in different forms. The output form presents a totality of visual objects on a screen of a personal computer's monitor. The output forms differ by their designation and by included components. The components are divided into: 1) supporting communication with the system: menu (text menu and pictures); information systems of assistance (names of windows, status lines, additional information), helps; 2) presenting results of the processing of information to the user and affecting on the demonstration of them. an important feature of the output form is its organization directed so that a totality of components should provide the multiaspect and commented representation on a particular task to which the output form is related. In other words, each output form is related to a particular task which determines the character of selection of components, methods of representation thereof and processing. According to their designation, output forms are divided into: supporting a technological process; providing reference information; representing results of the processing of information and affecting on demonstration thereof (set by the user). The support of two methods of the processing of obtained results by an interface is supposed as follows: on a standard scheme; optional. The both methods suppose the use of specified output forms. The practical use of the technology based on the suggested inventions is illustrated by an example below. The example is the processing of information materials obtained from "Draft Programme and Budget for 1996-1997, Document 28 C/5, UNESCO publication 1995" (in Russian). 19 information materials (text fragments) were separated for indexing. "User's profile" describing a user's information need relating to "Draft Programme UNESCO" was generated for indexing the materials. The profile includes 9 elements: 1. Broadening local possibilities of education including press, radio, TV, libraries, multimedia. 2. Renovating and deverification of the education system taking into account needs of culture originality of learners. 3. Promotion of efforts to find alternative systems of education including open and remote. 4. Accelerating the transfer and dissemination of knowledge through existing nets and exchange of data bases. 5. Preservation and protection of the world heritage of the humanity in forms of books, works of art and monuments of historical and scientific importance. 6. Modernization of museum infrastructures and improving educational programs with the purpose to use museums as places of continuous education. 7. Promoting so that technological innovations should meet needs of the developing of the production, dissemination of various and qualitative culture programs and other culture production. 8. Enhancing efforts on development of regional computer nets which can become the first step to creating "electronic fast highways" for developing countries. 9. Promoting the use of information and communication technologies in all fields of UNESCO competence. Elements of user's profile were accorded with fragments of "Program" during indexing. As an example of indexing, three fragments of text with elements accorded to them (a number - an order number of an index, symbol "*" - an indication of higher priority for an element of user's profile relative to other elements prescribed to a fragment) are given. Fragment 1. Project 01224 from "Large program 1". On the way to continuous education. In the frames of International project on technical and professional education (UNESCO) which was started in 1992, efforts on creating the net of national centers of UNESCO with purposes to activate an exchange of experience on questions of the policy in the field of technical and professional education, strengthening a national potential in the field of research and development, promoting access to data bases and information will continue as earlier. The stress will be made on measures for training personnel in such fields as preparing training plans and methods of training, training teachers, administrators, planners (with participation of UN ESCO MIPO) as well as on preparing materials on methods of teaching. In connection with Project "Natural scientific. technical and professional education for girls and women", the attention will be paid on promoting the equal access to the technical and professional education for girls and women and cooperation between the education system and the labour market in perspective of continuous education (with participation of UNESCO IBP). The edition of quarterly information bulletin UNESCO INFO in English and French is provided for. Elements 2, 4, 9 are accorded to the fragment. Fragment 2. Project 03127 from "Large program III. Development of culture, heritage and creative work". Special efforts will be made with the purpose to preserve culture movables and to improve museums' infrasructure. The assistance to states-members will be rendered relative to preparing lists, providing the preservation. the security and popularizing collections. In cooperation with ICCROM and ICOM, the attention will be attracted to training museum workers by strengthening or creating nets in other districts similar to net PREMA for African countries. The technical assistance will be rendered to developing countries with the purposes to create national museums as well as to provide them with computer systems and data bases (in cooperation with Agency on cultural and technical cooperation [ACCT] and [ALECSO]). To the fragment, elements 5, *6, 9 are accorded. Fragment 3. Project 03127 from "Transdiscipline projects". Training materials and information will be widely disseminated through government and nongovernment systems from the net of delivery such as for example, "Net Africa 2000", "Society Planet", clubs of UNESCO. The net of associated schools, organizations of youth and of women, social movements and organizations of teachers. The assistance in translating separate materials into national and local languages will be rendered. Agreements on cooperation will be concluded with organizations dealing with population and environment in different regions with the purposes to promote wide dissemination of available information being important for an appropriate audience. To this fragment, elements *1, 4 * 8, 9 are accorded. Local structures corresponding to the fragments are shown in Fig. 8. Because of the small number of fragments used for an example and nonrepresentive statistics on local structures, a statistic analysis on particular local structures is not considered. Further, an integrated graph (Fig. 9) was generated which was used as a base for evaluating and interpreting input information. The analysis of multiplicity of edges of the integrated graph permits to determine the most closely - or loosely-coupled problems. We give, as an example, one option of the analysis. At first, we consider the most closely-coupled relationships (edges of the greatest multiplicity) from all possible optional pairs of elements of user's profile. The first three pairs are separated for demonstrating an approach. They are 7-9, 1-9, 2-9. It should be underlined that the separating is performed by a program. Now we shall realize a similar separation of all possible optional combinations by three nodes of the integrated graph that is we shall consider all. possible subgraphs of the integrated graph with three nodes. The separation is also performed by an instruction of the user automatically. Considering a total value of multiplicity of edges of the obtained subgraphs, we can put them in the order of decreasing this value. Let's consider the first three obtained subgraphs. They are 1-2-9, 1-7-9, 2-3-7. Comparing results achieved for subgraphs of the integrated graph with two nodes and for subgraphs of the integrated graph with three nodes, we consider how the character of relationship of elements of user's profile is changed. Let's consider subgraph 1-2-9. It is the first subgraph on total multiplicity of edges from subgraphs with three nodes. (Further we call them "three".) The subgraph represents a situation created in course of indexing and reflects the fact that problems 1, 2, 9 have occurred the most interrelated in the user's opinion for given information materials. The user can consider by means of a program what exact materials have served as a base for generating the given subgraph. Further, comparing the given subgraph with the subgraph with nodes 7 and 9 (a leader from subgraphs of the integrated graph with two nodes, the user can make the conclusion that element 7 did not participate in generating the biggest "three" although the subgraph with nodes 7 and 9 is a leader among subgraphs with two nodes. It is obvious that the given process is iterative and can be applied to subgraphs with different number of nodes. the purpose of the given process is to give the user information discovering in what way elements user's profile are used in indexing and what relations are generated between them on results of the indexing. Iteratively evaluating the resulted relationships, the user obtains the characteristic of information materials applying to user's profile got under indexing. One of options to provide the user with information about subgraphs of the integrated graph is a "scheme of interrelationship"(Fig. 10) presenting to the user the information on particular elements of user's profile and their relationship visually. For "scheme of interrelationship", relations coupling elements of user's profile are edges of a subgraph and a quantitative evaluation of a given relation is an edge's multiplicity. Industrial Applicability The suggested methods can be utilized for achieving various practical results in different fields of use thereof, in particular: in fields of administrating, financing - revealing relationships between different indexes describing a process or an object of the user's interest, leading, forecasting, revealing arising problems; in a field of selfeducation - accelerated studying various materials on a complicated problem; in libraries - selecting information materials taking into account the user's interest on subjects, express acquainting with abstracts of materials interesting for the user, creating special data bases including semantic abstracts of publications on definite subjects; under creating systems for producing abstracts automatically in different languages.
