Razvili smo sistem za analizo besedil in ga osnovali kot dodatek za programsko okolje Orange. Orange združuje bogat nabor metod za nadzorovano in nenadzorovano strojno učenje, zato je odličen temelj za razvoj takega sistema. S pregledom literature in odprtih orodij smo določili kaj so temeljne metode, ki se uporabljajo na tem področju in na podlagi le-tega osnovali funkcionalnosti naše knjižnice. Dodali smo gradnike za zajem podatkov s spletnih virov kot sta PubMed in New York Times. Implementirali smo metode za predobdelavo, ki vključujejo pretvorbo besedil v vektorje, odstranjevanje odvečnih besed, lematizacijo in krnjenje, tok dela pa nato podprli z vizualizacijami, na primer z oblakom besed. Naš cilj je bil razviti gradnike, ki se med seboj dobro povezujejo z vizualnim programiranjem, so dobro povezljivi z ostalimi gradniki sistema Orange, ter jih je moč enostavno nadgraditi z razvojem novih gradnikov. We have developed a text mining system that can be used as an add-on for Orange, a data mining platform. Orange envelops a set of supervised and unsupervised machine learning methods that benefit a typical text mining platform and therefore offers an excellent foundation for development. We have studied the field of text mining and reviewed several open-source toolkits to define its base components. We have included widgets that enable retrieval of data from remote repositories, such as PubMed and New York Times. The pre-processing was designed to include transformation of documents to vectors, stop word removal, lemmatization and stemming. The results can be visualized via widgets such as the word cloud. Our goal was to develop widgets that can be easily incorporated into the existing Orange workflow, can be upgraded with additional widgets, and perform well in a visual programming environment.

V diplomskem delu je predstavljen razvoj večnamenske kmetijsko-gozdarske prikolice. V uvodu je podan splošen opis projekta, njegov namen ter zgodovina podjetja s katerim smo sodelovali. Na podlagi navedenih zahtev so določene najboljše rešitve za razvoj in nadaljnjo izdelavo. Opisani so procesi izbiranja ter konstruiranja vseh ključnih elementov s sklopi in so za en primer narejene tudi računalniške analize. Prav tako je opravljen plan trajanja aktivnosti in analiza le tega. Opravljen je tudi izračun stroškov. Ker smo prikolico razvijali na podlagi obstoječega izdelka podjetja Farmtech, ni bilo potrebno razviti celotnega stroja temveč samo elemente oz. sklope, kateri pri nadgradnji ne bi zadostili potrebam po vzdržljivosti, funkcionalnosti in varnosti. Zaradi zahtev po uporabi izdelka na najrazličnejših področjih smo se odločili za montažo dvigala, kateri zelo razširi spekter del. This diploma work is presented the development of agro-forestry multipurpose trailer. In the introduction a general description of the project and its purpose are given. Presented is a short history of the company with which we have cooperated. Based on requirements are selected and determined the best solutions for the development and further elaboration. It describes the processes of selection and design of all key elements and assemblies. For one example is done computer analysis. We also made a plan of duration activities and analysis of this project and calculated its costs. Because we developed the product, on the basis of an existing trailer, there was no need to develop the whole machine but only items or assemblies, which do not meet the needs for durability, functionality and safety. Due to the use of the product in a variety of areas, we decided to mount forestry crane, which considerably expands the range of works.
