Following the prevailing of the internet, the vigorous development e-commerce has given great impacts on traditional tangible stores and the whole marketing environments. Information Technology has not only changed our lives, but also changed consumers¡¦ behavior and marketing channels; and the e-commerce effect has already started to permeate into every stratum of business activities, including the exploitation, marketing, and after-sales service of new products, brings the industries infinite business chances. According to the reports of Institute for Information Industry, the market of internet shopping is going into its high development period, and as the idea of internet consumption disseminates gradually, the internet business transaction market of consumers¡¦ side also becomes an important internet business area. As the portal site operators think the environment of internet shopping in Taiwan as mature, now not only the B2C market seems full of potential, the C2C trend is also not far from breaking out. This research targets at the professional internet auctioneers who have used the auction websites to sell, exploratorily analyzes their operation strategy and performances. To be more specific, the main purpose of this research is to examine the relation between the individual characteristics, entrepreneurial motives, and operation strategies of the entrepreneur internet auctioneer and their operation performances, intending to realize if these differences in different economic situations would bring different influences into their performances. Accordingly, I chose the auctioneers of the 2003 best-scale auction website-Yahoo! as research objectives, using internet questionnaires and invited auctioneers to answer them, and finally gathered 155 valid samples to identify the relation between their marketing strategy combinations and performances. Various data statistic analyses including descriptive statistics, factor analysis, reliability analysis, Pearson correlations analysis and regression analysis are completed by SPSS Version 10.1. Through this research I find that in promotion strategies, if the auctioneers strengthen their sale skill and membership management system, the re-buy rate of members and the business volume can be heightened effectively; and by effectively holding the regular consumers, auctioneers can save a large amount of operation cost searching for new customers and thus can maintain their advantages in making profits. On the other hand, in product strategies, the auctioneers emphasize a lot in the best presentation of their product information (with pictures and texts), which obviously in turn helps them a lot in stimulating buying rates. Besides, the auctioneers also stress on the cultivation of their professional abilities and their knowledge about the products, along with the preservation of virtuous interactions with their customers, their operation performances can be enhanced even more.

Thesis advisor: Hideo Konishi / Online auctions have many different formats. Each of these affect the ways in which users bid strategically. One example of this is the end-time format. Some sites, like eBay, use a hard close, under which there is a strict end-time and the highest bidder at that time wins. Others, like Amazon, have an extended end-time format. It has been shown that these differences do, in fact, appear to change how bidders behave. This paper uses data obtained from Yahoo! Auctions, where both formats are used, to examine the impact these differences have on the final price of an auction. / Thesis (BA) — Boston College, 2005. / Submitted to: Boston College.

The purpose of this thesis is to evaluate three web-based search engines and compare the 10 first retrieved documents. We used the search engines Google, Yahoo! and Exalead. The evaluation is based upon 20 topics with strong polarized opinions and these have been derived from Swedish media and every day life. From these topics we have constructed the 20 queries used for searching. The 10 first documents are each placed in four different categories, For, Against, Neutral or Irrelevant. For and Against are opposed to each other regarding different opinions in the 20 topics. The purpose of this is to get a picture of the different topics, seen through the three search engines. Does one of the categories weigh more heavily than the other, represented in the 10 first documents? If this is the case, does the same category weigh more heavily in all three search engines, or how do they deviate from each other? The results showed that one of the categories, in most of the topics, weighs more heavily than the opposed category. The opposed category is in some cases not represented at all in the 10 first documents. In some of the topics, the same category weighs over in all three search engines, but in more than half of the topics the different search engines deviate from each other regarding the opposed categories. / Uppsatsnivå: D

This thesis is focusing on how global and local search engines retrieve information from the local domain. The three search engines tested are the global search engines Yahoo, Ask.com and the local search engine Web Wombat. The questions we examined were: which search engine has the best retrieval effectiveness? Could there be other reasons than retrieval effectiveness, to choosing a local search engine?For our test we constructed 20 questions related to Australia.We chose to divide the questions into topics like nature, sports and culture. For all questions we evaluated the relevance of the first 20 hits. We used the following measures in our test: Jaccard´s index, precision and average precision. We also looked at factors such as duplicates and error pages, because we consider this to be an important aspect to consider, when looking at the relevance of the first 20 hits. The results of our study showed that Yahoo had the best performance for precision. Web Wombat had faulty precision but results from Jaccard´s index revealed that Web Wombat had many unique documents. Web Wombat had the best average precision on one of our questions. In spite of Web Wombats faulty precision, we think that Web Wombat serve a purpose as an alternative to global search engines. / Uppsatsnivå: D

The purpose of this Master’s thesis is to evaluate three general query-based web search engines. The search engines chosen are Google, Yahoo! and Live Search. The topics, which where transformed into twenty queries, are based on real users’ information needs, taken from an ask-a-question service. For every search the first 10 hits in each of the three search engines were evaluated. The measures that have been used are precision and overlap. The queries were evaluated on a binary relevance scale with 0 or 1. Precision has been measured as average precision over 1-10 DCV levels for all 20 queries in the evaluation. It has also been measured as average precision in a query-by-query calculation over 10 DCV levels for each query and search engine. The number of duplicate links, dead links, mirror pages, relevant hits and irrelevant hits has also been recorded in the study for each search engine, for a comparison. Overlap was measured at two different DCVs, 1 and 5. Eventually the results show that Google had the best results regarding precision. It also had the highest number of relevant hits. Google and Yahoo! showed the highest overlap at DCV 1. At DCV 5 the greatest overlap was between Yahoo! and Live Search. / Uppsatsnivå: D

Recently, we observed many networked market are served almost by a single platform, and can called that situation be winner-take-all. We could observed that the top website occupy huge market, and still be the top for long time. Conversely, the other website only shares the tiny market. This paper chooses the biggest Taiwan portal Yahoo!Kimo to be the research case. In addition, the case object is its e-commerce department, which is the Yahoo! only e-commerce department worldwide. Through this case, we could find out the truth of winner-take-all. In this research, we use in-depth interview and combine with secondary data. According to past researches and the situation of Yahoo!Kimo, we address the research question as follow: (1) How does Yahoo!Kimo develop their e-store platforms to maintain their e-commerce leading position in Taiwan. (2) Is there a winner-take-all phenomenon on Yahoo!Kimo? After generalize the data, we found that although Yahoo! first time enters Taiwan not successful. Their strategy is merge different kinds website, such as the leading portal Kimo, the most visiting blog Wretch, and Monday.Tech. They got their human resource and technology sooner, then become the top one portal in Taiwan provides variety services for users. For foreign website and companies enter a new market will be a good role model. Moreover, we prove Yahoo!Kimo is role model of winner-take-all.
