The analysis of the hyper link structure of the web has led to significant improvements in web information retrieval. This survey describes two successful link analysis algorithms and the state-of-the art of the field.


Many of today’s researches are dependent mostly on browsing the internet for extensive studies. Related to this, many algorithms has been presented to evaluate the most effective way of linking related documents over the internet. The primary objective of information retrieval is that it must be closely connected to the query being searched. Since the internet contains unlimited source of documents and papers for related links, one cannot determine of how to rank the quality of each links.

People are able to browse topics and articles through the use of keywords. Search engines would then be generating related lists that have to do with the specified keyword. Considering nowadays, many search returns do not contain the necessary information or it is not appropriate to the subject. Countless websites are now being full and crowded of hyper links that tend to be unnecessary to the article. This is a waste of time and effort in the part of individuals since hyper links are lean to connect to other sites and thus creating distance to the main subject.

This paper showed three main algorithms on ranking the quality of a document, finding related pages and categorizing pages. Among these are (1) Query-Independent Connectivity-Based Ranking (2) Query-Dependent Connectivity-Based Ranking (3) Evaluation of Query-Dependent Rankings. The paper was able to discuss the methods of each ranking algorithms which can be useful in proper linking of documents in the web. By recognizing the strong point of each algorithm, one will know which is more effective than the other.

Historically birth outcomes have been relatively unpredictable to physicians and midwives. The development of systems dynamics computer simulation methods provided a tool through which prediction might be realized.


Prevention to any unexpected events is always a good way of avoiding a much greater effect than to wait until the time that it is already at hand. Pregnancy has been one of the most critical issues regarding health and family planning. By predicting consequences, one can better put the resources needed. The goal of prediction is to better allocate treatment resources and to prevent problems from occurring, both in terms of prevention before the fact and detection of problems in an earlier stage than previously possible. [1]

IT was able to stand there hold in producing many technology that do not limit only to the web but instead it made ways that can be applicable even to medical applications. The purpose of this research was to determine the potential usefulness of (Dynamics Computer Simulation Model) DSM for psychosocial and biomedical research and on predicting which women are at risk for premature labor [1].

The paper presented two ways in predicting and testing women who are suspected of pregnancy. One is the traditional way called Discriminant function analysis (DFA) that contains entry for evaluation such as race, drinking and other intakes of drugs of the previous years before pregnancy. DFA is compared to DSM which uses the simulation modeling in showing the possible cases of pregnant women. By creating these models, one can easily assess there behaviors as to change it to avoid unnecessary risks. Demonstrating this kind of simulation model can predict outcomes and can help women to reach there realization on giving up some practices to have a better birth carriage.

The evaluation of anti-virus software is not adequately covered by any existing criteria based on formal methods. The process, therefore, has been carried out by various personnel using a variety of tools and methods. Some of these tools and methods should be part of the evaluation process; others can provide misleading or damaging information resulting in increased exposure to computer viruses. [1]


Anti- Virus software is one of the vital need-to-have applications in one’s computer unit. The boost of many technological advancement in the industry also gave way to the maximum numbers of viruses as well as other things that damages or replaces the original contents of files and documents. As seen on the business market, there are many anti-viruses applications that are now developing to address the needs of individuals in preventing there files from unnecessary alteration and even to the extent of complete damage. At the present time, there are issues that arises, since there are many anti-virus programs, what measures can be handled and if these evaluation is credible according to the presented needs. The paper shows the drawbacks of many ways in which one relies his evaluation on the said anti-virus software, among these are (1) The Provider of Friendly Advice (2) The Employee (or the employee’s friend, colleague or Internet acquaintance) (3) The Computer Magazine (non-virus/security specific) (4) The Computer Security/Virus Magazine (5) The Independent Professional Evaluator (IPE) (6) The Commercial Evaluator (7) The Academic Evaluator (8 ) The New ITSEC Approach.

It also discussed the many problems occurring when selecting and certifying the quality of the anti-virus software. When reviewing softwares the evaluator and tester must not limit itself on the scope of the anti-virus but dig deeper and make a thorough study to show a high and qualified review on the said software. Thus, the reader is urged to use a wide variety of sources of information. Much of the information outlined above can be obtained at little or no cost; [2] by understanding the strengths and weaknesses of each different evaluation one can be in a position to extract figures which are relevant to determining which product is most suitable for the need of one’s company or institution.
