Επέκταση υπάρχουσας μηχανής αναζήτησης για δεικτοδότηση οποιωνδήποτε εγγράφων χρηστών

Φραντζής, Θρασύβουλος 08 March 2010 (has links)
Oι πληροφορίες που τροφοδοτουν τη βάση δεδομένων των Μηχανών Αναζήτησης προέρχονται από τον Παγκόσμιο Ιστό. Ένα τρέχων ζητούμενο στο πεδίο έρευνας των Μηχανών Αναζήτησης είναι η ανάπτυξη λογισμικού με σκοπό να δίνει την δυνατότητα στον χρήστη να δεικτοδοτεί προσωπικά έγγραφα έτσι ώστε παράλληλα να μπορεί να κάνει αναζητήσεις για εύρεση πληροφοριών και σε έγγραφα που προέρχονται από τον Παγκόσμιο Ιστό αλλά και σε προσωπικά του έγγραφα όλα δεικτοδοτημένα σε μία βάση. Αυτό είναι και το κύριο πρόβλημα που επιλύουμε στην παρούσα εργασία. Με την δυνατότητα αυτήν ουσιαστικά ενοποιείται η διαδικασία της αναζήτησης πληροφοριών στις δυο διαφορετικές πηγές πληροφοριών, τα έγγραφα του Παγκόσμιου Ιστού και τα προσωπικά έγγραφα του χρήστη. / -

Evaluation of Internet search tools instrument design

Saunders, Tana 03 1900 (has links)
Thesis (MPhil)--Stellenbosch University, 2004. / ENGLISH ABSTRACT: This study investigated Internet search tools / engines to identify desirable features that can be used as a benchmark or standard to evaluate web search engines. In the past, the Internet was thought of as a big spider's web, ultimately connecting all the bits of information. It has now become clear that this is not the case, and that the bow tie analogy is more accurate. This analogy suggests that there is a central core of well-connected pages, with links IN and OUT to other pages, tendrils and orphan pages. This emphasizes the importance of selecting a search tool that is well connected and linked to the central core. Searchers must take into account that not all search tools search the Invisible Web and this will reflect on the search tool selected. Not all information found on the Web and Internet is reliable, current and accurate, and Web information must be evaluated in terms of authority, currency, bias, purpose of the Web site, etc. Different kinds of search tools are available on the Internet, such as search engines, directories, library gateways, portals, intelligent agents, etc. These search tools were studied and explored. A new categorization for online search tools consisting of Intelligent Agents, Search Engines, Directories and Portals / Hubs is suggested. This categorization distinguishes the major differences between the 21 kinds of search tools studied. Search tools / engines consist of spiders, crawlers, robots, indexes and search tool software. These search tools can be further distinguished by their scope, internal or external searches and whether they search Web pages or Web sites. Most search tools operate within a relationship with other search tools, and they often share results, spiders and databases. This relationship is very dynamic. The major international search engines have identifiable search features. The features of Google, Yahoo, Lycos and Excite were studied in detail. Search engines search for information in different ways, and present their results differently. These characteristics are critical to the Recall/Precision ratio. A well-planned search strategy will improve the Precision/Recall ratio and consider the web-user capabilities and needs. Internet search tools/engines is not a panacea for all information needs, and have pros and cons. The Internet search tool evaluation instrument was developed based on desirable features of the major search tools, and is considered a benchmark or standard for Internet search tools. This instrument, applied to three South African search tools, provided insight into the capabilities of the local search tools compared to the benchmark suggested in this study. The study concludes that the local search engines compare favorably with the major ones, but not enough so to use them exclusively. Further research into this aspect is needed. Intelligent agents are likely to become more popular, but the only certainty in the future of Internet search tools is change, change, and change. / AFRIKAANSE OPSOMMING: Hierdie studie het Internetsoekinstrumente/-enjins ondersoek met die doel om gewenste eienskappe te identifiseer wat as 'n standaard kan dien om soekenjins te evalueer. In die verlede is die Internet gesien as 'n groot spinnerak, wat uiteindelik al die inligtingsdeeltjies verbind. Dit het egter nou duidelik geword dat dit glad nie die geval is nie, en dat die strikdas analogie meer akkuraat is. Hierdie analogie stel voor dat daar 'n sentrale kern van goed gekonnekteerde bladsye is, met skakels IN en UIT na ander bladsye, tentakels en weesbladsye. Dit beklemtoon die belangrikheid om die regte soekinstrument te kies, naamlik een wat goed gekonnekteer is, en geskakel is met die sentrale kern van dokumente. Soekers moet in gedagte hou dat nie alle soekenjins in die Onsigbare Web soek nie, en dit behoort weerspieël te word in die keuse van die soekinstrument. Nie alle inligting wat op die Web en Internet gevind word is betroubaar, op datum en akkuraat nie, en Web-inligting moet geëvalueer word in terme van outoriteit, tydigheid, vooroordeel, doel van die Webruimte, ens. Verskillende soorte soekinstrumente is op die Internet beskikbaar, soos soekenjins, gidse, biblioteekpoorte, portale, intelligente agente, ens. Hierdie soekinstrumente is bestudeer en verken. 'n Nuwe kategorisering vir aanlyn soekinstrumente bestaande uit Intelligente Agente, Soekinstrumente, Gidse en Portale/Middelpunte word voorgestel. Hierdie kategorisering onderskei die hoofverskille tussen die 21 soorte soekinstrumente wat bestudeer is. Soekinstrumente/-enjins bestaan uit spinnekoppe, kruipers, robotte, indekse en soekinstrument sagteware. Hierdie soekinstrumente kan verder onderskei word deur hulle omvang, interne of eksterne soektogte en of hulle op Webbladsye of Webruimtes soek. Die meeste soekinstrumente werk in verhouding met ander soekinstrumente, en hulle deel dikwels resultate, spinnekoppe en databasisse. Hierdie verhouding is baie dinamies. Die hoof internasionale soekenjins het soekeienskappe wat identifiseerbaar is. Die eienskappe van Google, Yahoo en Excite is in besonderhede bestudeer. Soekenjins soek op verskillende maniere na inligting, en lê hulle resultate verskillend voor. Hierdie karaktereienskappe is krities vir die Herwinning/Presisie verhouding. 'n Goedbeplande soekstrategie sal die Herwinning/Presisie verhouding verbeter. Internet soekinstrumente/-enjins is nie die wondermiddel vir alle inligtingsbehoeftes nie, en het voor- en nadele. Die Internet soekinstrument evalueringsmeganisme se ontwikkeling is gebaseer op gewenste eienskappe van die hoof soekinstrumente, en word beskou as 'n standaard vir Internet soekinstrumente. Hierdie instrument, toegepas op drie Suid-Afrikaanse soekenjins, het insae verskaf in die doeltreffendheid van die plaaslike soekinstrumente soos vergelyk met die standaard wat in hierdie studie voorgestel word. In die studie word tot die slotsom gekom dat die plaaslike soekenjins gunstig vergelyk met die hoof soekenjins, maar nie genoegsaam sodat hulle eksklusief gebruik kan word nie. Verdere navorsing oor hierdie aspek is nodig. Intelligente Agente sal waarskynlik meer gewild word, maar die enigste sekerheid vir die toekoms van Internet soekinstrumente is verandering, verandering en nogmaals verandering.

A behavioural data approach towards predicting direct real estate markets in the United Kingdom

Stevens, Donald Garth January 2018 (has links)
In recent years, modern prediction models have evolved to include behavioural data such as user-generated search query data that capture market sentiment and reach beyond the grasp of established macroeconomic indicators. These applications had considerable success in predicting a wide range of economic phenomena with the assumption that internet interaction behaviour resembles probable offline behaviour. Despite the considerable success of this approach, the existing literature argues for the continuous validation of search query keywords and its probable meaning over time to avoid spurious and biased results. Although recent literature attempted to bridge the keyword validation gap, this line of research is still in its infancy. This thesis sets out to examine the validity of web search intention to serve as a “pure” demand proxy for direct real estate market prediction in the United Kingdom. More specifically, it is directed towards constructing web search indices to explore: (i) the extent to which an individual’s true real estate orientated intentions manifest themselves in their web search behaviour and (ii) the magnitude to which real-time information adds value towards the prediction of illiquid asset classes. In doing so, a conceptual framework is produced, which outlines the logic and importance associated with intention specific web search in the digital age, as well as its relation to real estate demand. The empirical findings suggest that intention specific keyword development might be of little importance for aggregate housing and office market forecasts in the United Kingdom. On the contrary, it seems that the viability of intention specific web search keyword development increases when it is directed at a specific regional market. The overall thesis narrative introduces a new way of thinking about web search in the context of economic demand and draws from a variety of principles and methodologies to establish an avenue from which future research can be conducted.

Visibility of e-commerce websites to search engines: a comparison between text-based and graphic-based hyperlinks

Ngindana, Mongezi January 2006 (has links)
DISSERTATION Submitted in partial fulfilment of the requirements for the degree MAGISTER TECHNOLOGIAE in INFORMATION TECHNOLOGY in the FACULTY OF BUSINESS INFORMATICS at the CAPE PENINSULA UNIVERSITY OF TECHNOLOGY 2006 / Research has shown that most website developers first build a website and only later focus on the ‘searchability’ and ‘visibility’ of the website. Companies spend large amounts of money on the development of a website which sadly cannot be indexed by search engines, is rejected by directory editors and which is furthermore invisible to crawlers. The primary objective of this dissertation is to compare and report on the impact of text-based versus graphic-based hyperlinks on website visibility. The method employed in the research was to develop two e-Commerce based websites with the same functionality, contents and keywords, however utilising different navigation schemes. The one website had all hyperlinks coded in text-phrases, while the other embedded the hyperlinks in graphics. Both websites were submitted to the same search engines at the same time. A period of eight months was allowed to ensure that the websites drew sufficient ‘hits’ to enable a comparative analysis to be conducted. Two industry standard website ranking programs were used to monitor how the two websites feature in the search engine rankings. Graphs as well as text-based reports produced by the ranking programs and the t-test were used to compare and analyse the results. Evidence based on the reviewed literature indicated that there are conflicting reports on the impact of text as opposed to graphic hyperlinks on website visibility. However, there is unsupported evidence that text hyperlinks achieved higher rankings than graphics-based hyperlinks. Although the ‘human website browsers’ find a certain amount of graphical aids conducive to easier navigation, ‘search engine crawlers’ find many of these same graphic aids impossible to index. The study supported that the graphic-based website ranked higher than the text-based website, which calls for a balance to be found between these two extremes. This balance would satisfy both ‘human website browsers’ and ‘search engine crawlers’. It is posited by this author that this dissertation provides website designers with the abilities to achieve such a balance. KEYWORDS: search engines, hyperlinks, text, graphics, visibility, navigation, ecommerce, design.
