Computer Science论文模板 – Report on Information Retrieval for Europana

Name of information source and its URL

Information retrieval (IR) system is one of the most common ways through which the use of technology has enabled various individuals to access several databases.  Apparently, information retrieval is one of the surest ways through which individuals can access varied information from numerous websites. This report seeks to carry out an effective analysis of how information retrieval can be done from Europeana whose URL is www.europeana.com. The website is highly rated in Europe and acts as one of the major information sources for scholars across the globe. The website has 593 ratings and a total of 73 reviews. The website has information that can be accessed from any part of the world hence making IR easier.

Method

The best method that can be used in I.R for a website such as www.europeana.com is the use of key words. Basically, keywords are very essential in guiding the users and directing them to various related files that might have a name close to the keyword used in the search. First and foremost, it is quite imperative to ensure that the keywords used have direct relationship to the material being searched online. In searching for a book, for instance, Harry Potter’s books, it is essential to ensure that the search method takes a step that will help in giving the best results.

The method involves inserting a key word, for instance the word “Harry Potter” and clicking search. Consequently, the search engine will give a number of results from which the person searching the object will select the file that best fits their search and use the information therein. The rationale for the types of tasks selected will depend on the information that is being sought from such websites. It is crucial to ensure that the information being searched is directly linked to other pieces of information that are found in the website in question. In order to get the best results from the tasks searched in websites such as www.europeana.com, it is important to ensure that the keyword is correctly spelt to avoid finding information that is not directly related to the searched information.

Results of the search

The results of the test gave various books and articles that had any element of Harry Potter in them. Apparently, the results were very useful in giving the information that was being searched. From the numerous search results, it is clear that the search method used was highly effective in answering the questions that the search seek to find out. From the variety of results produced, one is able to filter the results in order to get the best material that they intended to use. The system performed the task faster by just loading the information for a few seconds and giving the results. In addition, a system like that of Europeana is designed in a manner that gives the users an opportunity to refine the results depending on what one is looking for.  A good example is given in the screenshot below that shows the various ways through which one can filter the search results to fit the material that they are looking for.

Evidently, some of the refined search options could include texts, images, videos, and sound among other file formats.  In addition, it is crucial to understand that the results also gave the users an option of filtering based on the years and country of origin of the material that was being retrieved. The system also performed the task by giving the name of the keyword searched in various languages that have created different versions of the searched item. The only problem that was experienced was the existence of a wide variety of information making it hard for a user to select the best piece (Manning Et al., 2007). Given on the process used, I can say the system is highly reliable and effective.

Analysis

The information retrieval system has performed reliably and given a variety of results that one can choose from. Basically, the results have shown how excellent Euroeapa search engine is and how best it can be used in various categories hence making it an outstanding system. The system has also shown sensitivity to various factors such as punctuation marks, and spelling mistakes.  In addition, there are a number of problems with the approaches that involve hyphens, digits and capitalization of titles being searched. It is quite imperative to explain the fact that the search engine also provides results for words that are not of English language. A good example is the search of the words “Del Amor’ which gives results with various titles and books. Admittedly, one can choose whatever they want to filter in the search by clicking on the navigation options available at the left side of the website (Schwartz, 2008).

Morphological analysis also reveals that the search using different word stems and spellings give almost the same results. Prudently, the results from the two tasks that involved the word “Harry Potter” and “Harry Poter” show a big difference in the search engine. Evidently, the correct spelling of the word gives more results compared to the mis-spelled word. Searching the word Harry Potter gives 597 results that all have the keyword in them within a short time while the word Harry Poter only gives two results. From the results, it is evident that one needs to be very sure on the spelling of the word being searched in order to get the most precise and useful results (Russell-Rose & Tate, 2013).

An elaborate analysis of the two results reveal that the results from the word “Harry Poter”  does not even  have any direct linkage to any works that were written by Harry Potter. Rather, it gives expansive and non-specific results on the official directory in Great Britain and Ireland.  From the results, it is important to make conclusions that in order to get the best results, one need to be pretty sure of the words being used in Information retrieval from websites such as europeana.com.  Based on the results, the analysis gives a more conclusive elaboration on how the results can be interpreted by various users of the website.

From the results retrieved using the keyword Harry Potter, it is evident that the numerous results show a great reliability in the website. However, opening the first result which is named Harry Potter und der Stein der Weisen, it is apparent that if one was looking for an English resource book on Harry Potter, then the first book might prove to be misleading. Besides, the writings are in German hence making it difficult for the readers who do not understand German to successfully use the resource. Nonetheless, one can navigate backwards on the webpage to get to the initial results and select another item that best fits their needs (Hearst, 2009).

Another result that one might find useful in case they were looking for resources written in English is Harry Potter and the quest for knowledge. From the results, it is clear that information retrieval from websites help the users in selecting the best material that they feel best suits their needs. Additionally, there are various international languages that one can select in order to make the search more refined (Rowley & Hartley, 2008).

Recommendation

From the results and analysis of the search results from europeana.com, it is essential to come up with various recommendations on how the aspect of information retrieval can successfully be done.  Notably, it is recommendable that the users of the search websites use precise and clearly spelt words in order to come up with the best results. In case a student is looking for a book, for instance, with the key words Harry Potter, it is important to ensure that they do not use wrong spellings that would complicate the results from the search engines (Choo, 2002)

Another major recommendation that needs to be looked at is the use of filters that are in the websites to ensure that the users of the websites do not get ambiguous results. For instance, if one is looking for an image from Europeana, there is no point in searching for general information when the website gives the user an option of filtering the results to get the most desired aspect. Additionally, it is recommended that the users of the websites be very keen when using punctuation marks and capitalization of certain words being searched.

Although the search engines always have close results, it is crucial to understand the fact that being precise is one of the reasons that would make one get exactly what they want. Indexing is another great factor that individuals need to implement in ensuring that the information being searched is retrieved in a systematic way. Obviously, indexing would help the users of the website in ensuring that they come up with a more elaborate procedure that can be used to gain access to more useful information.

It is also recommendable that the Information search process (ISP) follows a systematic flow that will help the users in having an opportunity to be more adept in their information search process. Usually, the process needs to follow the procedure that involves initiation, selection, exploration, formulation, collection and presentation. First and foremost, initiation would involve recognition of the actual need of the information. This step would then motivate the user to look for various online sources such as websites from where the need can be fulfilled. The second step would involve selection of a general topic or a given approach to the search.  Particularly, selection of a topic will be the major aspect that would guide the user in the given website. For instance, for the case of this report, the word selected was Harry Potter (Kuhlthau, 1991).

The third step is exploration which will enable the user to investigate the given topic and find out more about the topic from other possible sources. The fourth step is formulation which should be focused in coming up with various perspectives through which the topic can be analyzed. Collection of information is the fifth process which mainly involves visiting the said website for instance europeana.com in order to get the information that is needed for the study. The final step is presentation which mainly enables the user to present the pieces of information that have been searched from the website and the search results.
