Användning av Self Organizing Maps som en metod att skapa semantiska representationer ur text

Denna studie är ett kognitionsvetenskapligt examensarbete som syftar på att skapa en modell som skapar semantiska representationer utifrån ett mer biologiskt plausibelt tillvägagångssätt jämfört med traditionella metoder. Denna modell kan ses som ett första steg i utredningen av ansatsen som följer. Studien utreder antagandet om Self Organizing Maps kan användas för att skapa semantiska representationer ur stora mängder text utifrån ett distribuerat inspirerat tillvägagångssätt. Resultatet visar på ett potentiellt fungerande system, men som behöver utredas vidare i framtida studier för verifiering av högre grad..

Anva?ndning av markfuktighetskartor fo?r sta?ndortsanpassad plantering

Digital depth-to-water maps can be produced from a digital elevation model (DEM). Then GIS- based algorithms are used to calculate water flows and the depth-to-water index classes dry, fresh, moist and wet. The purpose of this study was to investigate the possibility to use depth- to-water maps for site adapted planting.The results showed that use of depth-to-water maps for site adapted planting, roughly halved the proportion of improperly planted surfaces from an average of 9 % to 4 %. The variation in the values of proper surface decreased and the result became more even.. In addition, more pine than spruce was incorrectly planted.

Google Maps som spelmotor för mobila plattformar

Spel kan utvecklas på flera olika sätt med flera olika utmaningar. I detta arbete undersökts det hur lämpligt det ?ar attutveckla och implementera ett spel tillsammans med Google Maps. Undersökningen testar hur det går att implementera vanliga element som förekommer i spel tillsammansmed Google Maps. Dessutom undersöks hur mycket dataanvändning som Google Maps använder för olika typer av kartor som den erbjuder.

Att Synliggöra det Osynliga : GIS som verktyg i sökandet  efter bosättningsområden från bronsåldern på Gotland

In this bachelor essay an attempt is done, to recreate a probable Bronze Age landscape on Gotland, with GIS as a tool. The landscape on Gotland is situated with many different monuments dated Bronze Age, such as cairns and stone ships. In creating of the maps, two possible shorelines contemporary with the Bronze Age have been calculated and marked on the maps. Furthermore, peat lands have been drawn upon the maps, by using the information from geological maps.A landscape variable have been compared between Bronze Age places and Early Iron Age houses; the soil type. On Bronze Age places gravel is the most common, while moraine marl is the most common on places with Early Iron Age houses.From a selection that were made, all Bronze Age places where within 3 km from the water, either the recreated shoreline or peat land.

Self-organizing maps ? en atlas över informationsrymden

The purpose of this thesis is to examine how semantic relations in a document collection can be visualized with a Kohonen self-organizing map. It can be seen as a map of the information space which can be used to support information retrieval. The study makes a comparison of the possible differences between a map that is based on morphologically unprocessed text and a map where the text has been lemmatized. The text that is being processed is the definitions of all the existing instances in WordNet of a random selection of indexing terms from the Times-collection. The purpose is to see if morphological processing somehow can show different semantic connections between term instances based on their definitions.

Digitala kartor för webben : En turistguide i 2D- och 3D

The city of Kalmar has a desire that their 3D maps of the city should come to a greater use and get residents more involved in Kalmar city. The purpose of this report is to show one way to work with these 3D maps when it comes to presenting information about Kalmar for its residents and tourists in a specific area.  The report also includes information about advantages and disadvantages with the use of 2D and 3D maps in different environments. Various reports and other sources indicate an interest in 3D and a use for this, but even that 2D is still seen as a natural way to read a map. By collecting information from relevant literature, interviews and user testing, the group has obtained sufficient background information to present the results of a web site, where the visitor can navigate in both 2D and 3D in a specific area of Kalmar. User tests and surveys have been conducted in two rounds and the web site has been revised after their results..

Kvantifiering och kartering av föroreningstransport inom ett avrinningsområde

The aim with my master thesis is to develop and test the applicability of methods to quantify and map solute advective travel times and pollutant transport at the catchment scale. Such quantification and mapping can increase the understanding of catchment-scale pollutant transport in general and contribute to the identification of the main sources of water pollution and the most efficient measures to reduce such pollution. The study area is the catchment of Oxundaån, about 20 km north of Stockholm. For detailed GIS modeling of water flow and catchment-scale contaminant transport in water, I´ve used new high-resolution elevation maps, land cover maps and soil maps combined with other available relevant data..

Kan talspråk integreras inom kunskapsorganisation? Problematiken med talspråk som bibliografiskt språk

Writing has been the most important tool in knowledge organization KO. In our modern society we can use our speech as a technical tool to seek information. Can we apply speech as a tool to organize information? The aim of this masters thesis is to problemize speech aspects in the field of knowledge organization KO. The investigation has two main parts and I use a hermeneutic approach.

Första avstampet för att konstruera en digital stadskarta för personer med nedsatt syn

The physical map that has been used until now can in the modern days be replaced with digital maps available in smart phones and tablets. One disadvantage of both is that the digital maps require the user to have a fully functional sight. The problem with the research done so far is that it provides little explanation as to why developers have decided to design the maps in a specific way. This thesis has been designed to address this problem.In order to provide the knowledge needed, a literature study was done to construct interview questions to an employee from SG Access AB. These answers and the literature study were used to construct interview questions to members and employees from Synskadades Riksförbund  (SRF).

Från papper till pixel : Kvarnholmen studerad utifrån historiska kartor med stöd av GIS

Sweden has a long tradition as a mapmaking nation. Tens of thousands of historical maps,dating from the sixteenth century and onwards are still preserved in archives today, providinga rich resource for studies of city growth and changes in the landscape through time. For morethan ten years an effort has been made by public authorities to transfer this material frompaper onto digital media. Due to modern technology, as for example GeographicalInformation Systems (GIS), researchers have been given improved possibilities to study andanalyze this material. This study uses a qualitative approach, based on both literature studiesas well as map studies.

Karttillämpningar för rikstäckande accessnät

Denna rapport aterger arbetsprocessen kring att utvärdera geograskatjänster, och att utveckla karttillämpningar för nätverk av rikstäckande omfattning. Arbetet utfördes pa plats hos DGC, en datakommunikations-, tele- och nätoperatör som distribuerar kundförbindelser i hela Sverige där konsumenter ansluts till stamnätet. Uppgiften bestod av att utvärdera möjligheter till att slå upp koordinater för etablerade kundplatser, rita ut accessnätet i ett kartgränssnitt och ta fram ett eller flera stödverktyg för bland annat orderprocesser. Användningsfall utifrån önskemål, arkitekturmönster samt analys av yttre leverantörers tjänster för geocoding avgjorde hur det slutgiltiga systemet var utformat. Mjukvaran som utvecklades integrerades både i bentliga system och som ensamstående tillämpningar.
