The planning can be found here:
A Personal assistant (PA) works closely with a person to provide administrative support, this support is usually delivered on a one-to-one basis. A PA helps a person to make the best use of their time because they limit the time spent on secretarial and administrative tasks. unfortunately having the luxury of a personal assistant is reserved for the rich and successful only, this is because of the one-to-one nature and the extensive knowledge usually required to perform PA tasks successfully. Less fortunate people have to take on these tasks themselves costing them time which could be spent on their core business, which can lead to stress and discomfort. The goal of this study is to map current novelties in this field, find new areas of improvement from them and (hopefully) making a prototype, incorporating these improvements, such that it is able to handle almost all the tasks of a PA. Also this prototype would improve itself by learning what each specific user expects from a PA.
Who are the users?
Many people would benefit from being relieved of their secretarial and administrative tasks. The users that benefit most from a PA would be the users that have to devote a lot of their time to make sure that their administration and agenda are updated regularly. Users that fit this criteria are for example people that work in the management sector. These users often arrange and visit meetings which require quite a bit of planning. Another key group of users is the group of students. Knowing when a lecture begins or when that important deadline approaches or even when a student needs to be free from distractions are operations where a PA is useful. This study will direct its attention on the student user group.
Requirements of the users
- The system should run on pre-owned devices
- The system should communicate with existing university infrastructure
- The system should manage the agenda of a user (e.g. notifications of upcoming deadlines, lectures and exams)
- The system should filter important information out of incoming messages. (email, whatsapp and canvas notifications)
- The system should, when desired by the user, correspond on behalf of the student.
- The system should tune its intrusiveness based on the users feedback
In this chapter we look at the potential impact of the product of our research. If our product fully works and solves the problem described in the problem description, it can have a great impact on the users of the product and the society as a whole. beneath is described what impact our product can have on the users, society and possible relevant enterprises.
The users of the product will, as described above, primaliary be students, but it can also be extended to anybody with a smartphone who receives more messages than desired but does not want to miss out on any potentially important messages. When a person no longer has to spend time on reading all seemingly unimportant messages or scan through them looking for important messages, they will have more time to spend on things they want to spend their time on. This is a positive effect of our product as this allows the user to focus on their core business. However, our product might also have different effects on the user. Scanning texts messages or text in general for relevant information can be a valuable skill to have, as it has also applications in other scenarios, such as scanning scientific articles or reports for important information. When an AI takes care of this tasks, users might lose this skill. This might hinder them in the other scenarios as described above, where the AI possible can not help them find the important information. Another negative consequence might occur when the AI does not work perfect, but the user trusts it to work perfect. In this scenario the user might miss an important message, which can have quite some consequences. In a work environment this can mean that the user does not get informed about a (changed) deadline or meeting. In a social environment this can lead to irritation or even a quarrel.
When we are talking about society, we are talking about all people - users and non-users of the product - combined and everything included that comes with that. To look at what impact our product might have on the society, we look at how relations between individuals chance, as well as how the entire society together behaves. The consequences described above can be extended to a society level. If people become more productive as described above, it certainly would benefit society, as more can be accomplished. The fact that people might lose the ability to quickly scan text to find important information can also have an impact on society. If an entire generation grows up like this, there will also nobody to teach it to younger generations, meaning that society as a whole will lose this skill. Now it can be questioned how relevant such a skill might still be in future society, but its a loss nonetheless. Another thing that might occur when a large public uses our product is that nobody longer reads all the seemingly unimportant messages. If nobody reads them anymore, those who write those messages will probably stop doing so, removing the purpose of our product.
possible relevant enterprises might be those who are interested to buy our product. This could be either a company like WhatsApp themselves, who want to integrate it in their application themselves, or a third party that wants to publice it as an application on its own. The companies, especially a third party, would want to make profit of such an application. companies like WhatsApp could offer it as a free service to make sure users keep using their application and possible attract new users. Third party companies can not do this and would need to find another way to make profit of the application. An easy solution for this seems to make the application not free of charge.
To have a more insight in what we want to accomplish we start our project with making a State-of-the-art. By doing this we acquire the knowledge to do a good study on what we want to accomplish. When this is clear we will start making a prototype. And thus implement the results that we got from our research. When this prototype is working we will reflect on the goal of the project, hereby also comes improvement to the prototype.
State of the art research
Understanding adoption of intelligent personal assistants: A parasocial relationship perspective
The article is about intelligent personal assistants (IPA’s). IPA’s help for example with sending text messages, setting alarms, planning schedules, and ordering food. In the article is a review of existing literature on intelligent home assistants given. The writers say that they don’t know a study that analyzes factors affecting intentions to use IPA’s. They only know a few studies that have investigated user satisfaction with IPA’s. Furthermore is the parasocial relationship (PSR) theory presented. This theory says that a person responds to a character “similarly to how they feel, think and behave in real-life encounters” even though the character appears only on TV, according to the article. Lastly is there a lot about the study in the article. The hypotheses of this study are: H1. Task attraction perceived by a user of an IPA will have a positive influence on his or her PSR with the IPA. H2. Task attraction perceived by a user of an IPA will have a positive influence on his or her satisfaction with the IPA. H3. Social attraction perceived by a user of an IPA will have a positive influence on his or her PSR with the IPA. H4. Physical attraction perceived by a user of an IPA will have a positive influence on his or her PSR with the IPA. H5. Security/privacy risk perceived by a user of an IPA will have a negative influence on his or her PSR with the IPA. H6. A person’s PSR with an IPA will have a positive influence on his or her satisfaction with the IPA. H7. A person’s satisfaction with an IPA will have a positive influence on his or her continuance intention toward the IPA.

Generative and Discriminative Text Classification with Recurrent Neural Networks
This article analyses the difference between discriminative and generative Recurrent Neural Networks (RNN) for text classification. The authors find that the generative model is more effective most of the time, while it does have a higher error rate. The generative model is especially effective for zero-shot learning, which is about applying knowledge from different tasks to tasks that the model did not see before. The discriminative model is more effective on larger datasets. The datasets that are tested range from two to fourteen classifications.
SMS spam filtering and thread identification using bi-level text classification and clustering techniques
The problem that this article is addressing is the large amount of sms messages that are sent and that identifying spam or threads in these messages is difficult. First the spam is classified, which could be done with one of four popular text classifiers, NB, SVM, LDA and NMF. These are all binary classification algorithms that either work with hyper planes, matrices or probabilities to split up the classes. Next, the clustering is applied to construct the sms threads, which is done by either the K-means algorithm or NMF. The results of the article are that the choice of the algorithms is very important. The algorithms used in the experiment are SVM classification and NMF clustering which give good results.
Spam filtering using integrated distribution-based balancing approach and regularized deep neural networks
This article is about creating a spam filter with the help of a Recurrent Neural Network. The spam filter is intended for both SMS and email. The network is tested on four spam datasets, Enron, SpamAssassin, SMS and Social Networking. The experiment starts by pre-processing the datasets such that there are only lower cases, no special characters and no stop words, since these contain no semantic information. The results of the experiment are compared with the following spam filters, Minimum description length, Factorial design analysis using SVM and NB, Incremental Learning, Random Forest, Voting and CNN. The results of the experiment are that the model is better on three of the four datasets by a small amount and the accuracy is around 98% for the three and 92% for the last one.

The Art and Science of how spam filters work
This article explains the principle of blacklists which analysis the header of a message to determine whether something is spam. Also messages that contain statistically dangerous files, such as .exe files, are often automatically blocked by content filters. The article end with a piece about Machine Learning in spam filters. Algorithms used in these filters try to find similar characteristics found in spam.
The Effects of Different Bayesian Poison Methods on the Quality of the Bayesian Spam Filter ‘SpamBayes’
This article discusses how spammers try to elude spam filters. The principle works as follows: add a few words that are more likely to appear in non-spam messages in order to trick spam filters in believing the message is legitimate. This article illustrates that even spam evolves, and as a result filters have to evolve with them.
