Knowledge based jobs introduced the logical formulas in the form of trees, but that little resemble the modern semantic network. Another pioneer was the Charles Sanderz Ac, who used the image recording in organic chemistry.
He formulated the rules of the findings using ekzistentsionalnyh graphs.
In psychological influence Зельц used the space for the submission of certain hereditary characteristics in the hierarchy of concepts. Research of knowledge based jobs had a tremendous impact on the study of tactics in chess, which in turn influenced such thinkers as Simon and Newell.
With respect to linguistics, the first scientist involved in the development of graphic descriptions became Tener. He used a graphic record of its grammatical dependencies. Tener had a great influence on the development of linguistics in Europe.
For the first time, knowledge based jobs have been used in machine translation systems in the late 50's - early 60's. The first such system that has created Masterman, includes 100 primitive concepts such as, for example, the people, a thing, DO NOT. Using these concepts, she described the level of 15000 units of the dictionary, which also had a mechanism for transfer characteristics with gipertipa to subtype. Some systems of machine translation based on the correlation networks Tsekkato, representing a set of 56 different relationships, some of which - declensional relations, subtype relations, member and part of the whole. He used a network consisting of concepts and relationships to guide the actions of parsing and resolving ambiguity.
In knowledge based jobs systems, semantic networks are used to answer various questions, explore learning, remembering and reasoning. In the late 70's networks have been widely disseminated. In the 80 boundaries between networks, frame structures and linear forms of writing are gradually disappearing. Expressive power is no longer a decisive argument for choosing networks or linear forms of writing because the ideas recorded on one form of records can be easily transferred to another. Conversely, particularly important were secondary factors such as readability, efficiency, neiskusstvennost and theoretical elegance, also takes into account for knowledge based jobs the ease of introduction into the computer, editing and printing.
