The shipping of the commercial products that contain a lexicon leads to the new as well as somewhat responsibilities that are unexpected. One of the major issues which has required the important debates and thoughts are offensive words. The consumer community views some of the words like patently offensive. It has been obtained by the Microsoft team that the lexicon from spellchecker that contains many of the offensive terms unfortunately. The spellchecker has the ability to mark each of the incidents that are related to any of the offensive terms that are misspelled that might lead for ridiculing as well as becomes also a form of the censorship. However, if there needs to add words to the lexicon of the spellchecker at the time someone misspells the some of the same words there is the chance that an offensive word could show up in list of the corrections that are suggested. These problems are avoided by the spell-checker with the addition of one single bit/ word. For the handwriting recogniser, his life is not so much easy. This is not having the ability to perform two jobs. This can just give the outputs of the possible recognitions into the list of top ten for displaying in the writer window. Whether, this can mark one word as restricted, the recogniser of the handwriting is not able to use this, the reason behind this is, at any of the time the constitutes can offer this as one recognition. Thus, the one and only solution that is for removing the word that is from the lexicon. A randomly selected 1000 words has been filtered by the Microsoft teams, covering scatological and sexual terms, ethnic and racial slurs as well as blasphemy. The reason behind this is an out of the dictionary system can be supported by the lexicon for covering the things as part foreign names, numbers and so on. The consumers are able to write still the terms that are offensive, however they have to handprint them so neatly. All of that has been removed actually is support to the sloppy cursive writing of the terms that are offensive.

Exercise 2:

1. In the paper, “Preliminary Experiences with a Tablet PC Based System” the authors have demonstrated that there was so much research on the advantages of the collaborative and active learning as well as on the use of this in the courses related to the computer science. As the classroom related innovations become much prevalent, this is natural for developing systems which can support the utilizations of the techniques. The authors have developed a kind of a system as the extension for the classroom presenter as well as to another system that is tablet PC based. The that system the students or the group of students can be equipped with the tablet pc based computers as well as at different points at the time of lecture, the students are asked for solving one problem or respond to the questions. The students can respond through writing the solutions of them on their tablet as well as submitting that wirelessly to the instructor. After that the instructor can review the responses of the students, then they can select one or even more students for displaying to the classes as well the annotated responses. The responses of the students can also be saved for reviewing after the lecture that was given by the instructor or even it can be made electronically available to the pupils. In this paper the authors have also described the system as well as their experiences while using the systems into two classes (Computer Ethics and CSI) at the University of San Diego in Fall 2003. The authors have also implemented extension for the Presenter that is known also as the student submission that enables the pupils to equip with the Tablet PCs for contributing to as well as for participating in the lecture. The submission of the students can be captured as separate slides on the machines of the instructor as well as can be previewed and displayed selectively to the class.
2. Thus it can be concluded that, in general the benefits that could be derived by using active learning and the unique use of it in the classes of computer science is thoroughly discussed in this research scope. The technology developers, instructors of computer science and the students are placed uniquely in such a position that they could adopt the required technology to support the class room active learning. Such system was developed and implemented to express the early experience. Though the deployment that was done in initial phase was small enough, but it was able to support collaborative and active learning in the classroom of computer science. With the help of this system, students got the capabilities to deal with the general mistakes and in response came up with a wide array of solutions for the same as well as different issues, the advantage of the rich environment was also taken to express their thinking, and got benefits from the activities of the instance. When students take part in those activities by attending a lecture, there is a chance of sharing their ideas and thinking with the whole class by asking him to write down his solution on the board or to show off using projectors. The happening of the solution share can offer a number of benefits. The students get re-assurance by observing others whom are committing similar type of mistake and get enlightened by observing the others who are coming up with elegant and particular solution. Asking different students to expose their solutions helps them to get familiar with viewpoint diversity and avail a platform to compare the approaches, which are related to same problem. The same case serves the teacher as well, through give him the opportunity to assess the student’s understanding related to that particular topic. This paper describes about a system that is Tablet PC-based that ensures the collaborative and active learning in the classroom of computer science. In this research procedure all the instructors and students were provided with a laptop, and at the spell of lecture any of the students were asked to come up with solution to the problem or to note down their answer on the tablet. Then the submitted responses of the students were displayed to the class by the instructor.
