Some test fees may be waived by the administrator to encourage users to establish high ratings.
  • the user may interactively select the desired test and, in this case, at 1004 the system deducts a certain amount of points from the account of the user as a fee for taking the selected test . Thereafter, at 1005, the user is tested and his/her interactive answers are analyzed by the system. Based on the test results, the system adjusts the user's rating in accordance with his/her performance on the test. See 1006.

Further, as shown at 1008, if the examination results were exceptionally good, to encourage such users to actively participate in the service, the user receives a certain number of bonus points. Finally, at 1009 the updated profile including user' s examination results and his/her new rating is displayed to the user.

  • the user selects the option of providing a proposal and describes the task for which he/she needs an expert.
  • the user specifies the selection criteria, preferably, by identifying qualifications, availability and costs of an expert that the user desires to retain for the project.
  • the system searches its database of user profiles and identifies the experts which most closely meet the user's requirements by matching, within a given degree of accuracy, the user's requirements to the stored profiles of experts specifying their qualifications and preferences.

If a given expert chooses not to respond (see 1106) , an appropriate notification is provided to the originator of the proposal as shown by 1107. Otherwise, if an expert responds to the proposal, the points are deducted from the account of the expert as a fee for participation as illustrated at 1108.
  • the originator of the question receives expert's response at 1109.

  • Figure 12 illustrates administrative functions supported by the system of the preferred embodiment .
  • One of these functions is monitoring the quality of the answers. (1201) This can be accomplished by periodically reviewing the answers, and if the answers are inadequate, changing parameters of the service so as to improve quality.
  • Point allocation 1202 and rating mechanism 1203 are discussed in further detail subsequently.
  • Another function performed by the system is, as discussed before, matching questions and answers.
  • the system stores the history of questions and best answers in the question-answer database.
  • this database is searched in order to locate an appropriate answer if a similar question had previously existed.
  • a variety of techniques known to persons skilled in the art can be employed to perform such a search, including an appropriate keyword or full text search.
  • the system provides facilities for user communications, e.g., internal system mail can be sent among the users.
  • user communications e.g., internal system mail
  • users may communicate so as to clarify questions and negotiate point values of the answers.
  • the communication provided by the system is anonymous i.e., identities of users are not revealed in e-mails. Only the user profile database stores true identities of the participants .
  • the system also provides arbitration so as to facilitate an agreement on the value of a task. Such an arbitration is particularly useful for larger tasks that require a request for a proposal as discussed above.
  • the system also stores and manages profiles of its users in the user profile database. This profile management includes storing account histories and point allocations for the users, as well as user's preferences and expertise in various areas.
  • Fig. 13 illustrates how the system allocates the points payable in connection with an answered question.
  • the preferred distribution scheme splits the question point value three ways. The points are divided between (1) the person(s) who answered the question; (2) the service administrator as a fee, and (3) the originator of the question.
  • the weights associated with the split are established by the service administrator. Preferably, the greatest share of the points is paid to the selected respondent (s) and the administrator's share is the smallest. In some embodiments the service administrator may receive no fee.
  • the points credited back to the person who asked the question serve as an incentive for informing the service of the best answer (s) .
  • This distribution scheme can be adjusted, for example, so that the points paid back to the originator of the question can be increased to provide a higher incentive at the expense of lowering the service administrator's fee. If no one answers a question, depending on the trade-offs of a given embodiment, the points can be credited back to the user less the service fee or can be divided equally among all the participants or handled otherwise based on the decision of the service administrator.
  • the system ascertains the point value and based on the stored distribution scheme (1302), increments the accounts of the users whose answers were picked (see 1304) , credits the points to the account of the originator of the question (see 1303) and also credits the points to the service administrator's account (see 1305).
  • the exact allocation depends on the trade-offs of a particular embodiment as understood by a person skilled in the art. If more than one answer was selected, the points are divided between all the chosen respondents preferably so that people who provided better answers receive more points.
  • Fig. 14 illustrates an adjustment of users' ratings.
  • questions with high point values or more difficult questions have a greater positive impact on the rating than questions with lower point value.
  • Ratings of respondents can be determined in various ways depending on the trade-offs of a specific embodiment and the factors not mentioned here may be used in other embodiments. For example, the frequency of responses in addition to the point value associated with them may be used. Or, to encourage users to answer questions, some questions may be branded as rating enhancing. That is, an answer to such a question has a disproportionally higher effect on the rating relative to the question point value.
  • Fig. 14 The factors effecting the user rating are illustrates in Fig. 14.
  • the rating of this user decreases. In other words, a user cannot be inactive over a relatively long period of time and still have a good rating.
  • the ratings increase if user's answer is picked as one of the best answers.
  • the increase in rating is proportional to the point value of the question asked. The increase may also depend on the importance attached to the question by the service administrator.
  • the difficulty level of the exam is taken into account in the rating process. See 1403. As shown at 1404, if previous answers and questions of a user are frequently chosen, the rating is also improved.
  • Fig. 15 illustrates searching of the database of questions and answers. Users may perform such a searching for a fee. As shown at 1501, a new question is searched against the database records using search technology known in the art. It should be noted that there is a concrete incentive for people to enter keywords and metadata in connection with questions and answers, because they are rewarded when a stored answer or question is located and chosen. When the answer to a question having a low point value is found in the database in connection with a previous question, having a higher point value, an intermediate stage of negotiation may be needed as illustrated as 1502 to provide proper compensation. Alternatively, the system may be set up without allowing this addition negotiation. At
  • the system displays the search results and at 1504 the user chooses the desired answer(s), if any.
  • Figs. 16A-H illustrate an example of sample electronic forms that may be used by the service. Different forms can also be employed as understood by a person skilled in the art. The forms also show illustrative information.
  • Fig. 16A shows a sample main menu form and Fig. 16B shows a sample form that enables a user to enter a question. A form for c modifying a question is similar to the form shown in 16B.
  • Fig. 16C is an example of a display of a list of questions provided to a user.
  • Fig. 16D shows a sample electronic form used for answering a question.
  • Fig. 16E shows a sample electronic form listing active questions of a user.
  • Fig. 16F is a sample electronic form for received answers and Fig. 16G 0 shows a sample electronic form for sending a message.
  • Fig. 16A shows a sample main menu form
  • Fig. 16B shows a sample form that enables a user to enter a question.
  • 16H shows a sample display of a list of messages.
  • the ratings can be based on consistent useful contributions made by users. Consistency is encouraged by 0 decreasing ratings with the passage of time. Thus, to maintain a high rating, a user should consistently provide the answers that are picked as the best ones. Also, a higher quality of responses can be maintained if user's rating decreases when his/her answer is not picked, particularly if the chosen answer is provided by another user with a lower 5 rating. Conversely, user's rating should increase more if his/her answer is chosen over an answer of another user with a higher rating.
  • An originator of the question may be provided with a 0 capability to enter comments when choosing an answer. Such comments can also be used to supplement ratings because they may help other users to better discriminate between answer choices on the basis of the ability of the respondents.
  • Ratings may be expressed as numerical figures or as qualitative descriptions. For example, there can be five levels of a qualitative user rating: wizard, expert, knowledgeable, layman, oblivious. Percentiles can be used for numerical values. So a rating of 50 percentile means that 50% of users are better than this user. In general, the service should aim to normalize the rating, so as to enable a comparison between users.
  • an implementation may impose a cost on answering a question. This cost can be a minimal point deduction which is refunded if the answer is selected.
  • the originator of the question may specify this cost as an optional attribute to a question, to make sure that only serious respondents contribute answers .
  • a user may notice a question that he/she would like answered as well.
  • An implementation may allow that user to add points to the question's point worth, thereby making the question more valuable to be answered. This user would then receive answers to the question as well, and respondents to such questions will have a greater incentive to provide good answers .
  • An implementation may impose a minimum price for asking a question. This may be needed so as to keep the point worth of the questions at a level where it is worthwhile for users to answer them. This minimum price should not be more than the number of points the implementation chooses to give new users, so as to enable new users to use their introductory points to ask at least one question. Also, an implementation may choose not to award these introductory points .
