Tématem této práce je sémantické vyhledávání ve velkých textových datech. Cílem je navrhnout a implementovat vyhledávač, který se bude efektivně dotazovat nad sémanticky obohacenými dokumenty a prezentovat výsledky uživatelsky přívětivým způsobem. V práci jsou nejdříve analyzovány současné sémantické vyhledávače, spolu s jejich silnými a slabými stránkami. Poté je přednesen návrh nového vyhledávače s vlastním dotazovacím jazykem. Tento systém se skládá z komponent pro indexaci a dotazování se nad dokumenty, management serveru, překladače pro dotazovací jazyk a dvou klientských aplikací, webové a konzolové. Vyhledávač byl úspěšně navržen, implementován i nasazen a je veřejně dostupný na Internetu. Výsledky práce umožňují široké veřejnosti využívat sémantického vyhledávání.

The purpose of this survey has been to investigate whether there are contradictions between user experience (UX) and search engine optimization (SEO), also called Google versus users. Professionals, in UX and SEO, have been asked to respond to a questionnaire regarding text and images within these two aspects. In addition to the professionals, users have also been asked to answer questionnaires and taken part in two different websites to investigate how text and images related to the previously mentioned aspects. The content on the sites has been the same but the design itself has been different, one has focused on UX - user experience and the other has been towards SEO - search engine optimization. The results of the study have not been distinctwhether there are contradictions between Google and users among professionals. Even in the relationship with users, how they experienced the different sites, there were contradictions between these two aspects. The conclusion is thus that it depends a lot on who views the website and his or her personal preferences. / Syftet med denna undersökning har varit att undersöka om det finns motsättningar mellan användarupplevelse (UX) och sökmotoroptimering (SEO), även kallat Google mot användare. Yrkesverksamma, inom UX och SEO, har fått svara på en enkät angående text och bild inom dessa två aspekter. Förutom yrkesverksamma har även användare fått svara på enkätfrågor och tagit del av två olika sajter för att undersöka hur text och bild förhåller sig mot tidigare nämnda aspekter. Innehållet på sajterna har varit detsamma men själva utförande har varit olika, den ena har fokuserat på UX –användarupplevelse och den andra har varit mot SEO – sökmotoroptimering. Resultatet av studien har inte varit entydigt om det finns motsättningar mellan Google och användare hos yrkesverksamma. Även i förhållandet med användare hur de upplevde de olika sajterna fanns det motsättningar mellan dessa två aspekter. Slutsatsen blir således att det beror mycket på vem som betraktar webbplatsen och dennes personliga preferenser

Studier visar att kunskapen och erfarenheten av marknadsföring inom små och medelstora företags (SME) till stor utsträckning är ganska dålig. Det finns inga riktlinjer för hur SME inom byggbranschen bör arbeta med marknadsföring och hur företagen bör överväga att digitalisera marknadsföringen för att kunna nå ut till en större potentiell kundgrupp. Dessutom nämns att fler människor börjar använda sig av internet och i takt med detta så blir det allt viktigare för SME att följa med i den digitala utvecklingen. Därför är det viktigt att undersöka vilka faktorer som påverkar SMEs inställning till användandet av sökmotoroptimering (SEO).    Tidigare studier visar att det finns ett flertal faktorer som påverkar inställningen hos SME att använda SEO. Ett antal av studierna är skrivna tidigare än år 2015 och efter litteratursökningen, så finner vi inga senare studier inom det berörda området om vad som påverkar processen för införandet av SEO hos SME inom byggbranschen som en kontext.  Data har samlats in genom sju utförda intervjuer med lika många företag. Insamling av data har skett via digitala intervjuer tillsammans med personal som har god insikt i företagets strategier för digital konsumentpåverkan. Data har sedan analyserats genom en kvalitativ innehållsanalys tillsammans med tidigare studier inom området.   Studiens resultat identifierade tre teman vilka var ekonomi där faktorer såsom finansiella resurser och branschens inställning innefattas. Det tekniska temat med faktorerna, andra digitala marknadskanaler och snabbare etablering samt temat kunskap där faktorn inställning hos medarbetare belyses. Flertalet av de identifierade faktorerna bekräftas av vad tidigare forskning bidragit till samtidigt som nya fynd har gjorts. Efter en analys av faktorerna så kom vi fram till att varje enskild faktor kan ha en direkt inverkan för valet hos SME att införa SEO som ett verktyg för digital konsumentpåverkan. Resultatet visade på att faktorerna ofta samspelar med varandra och verkar växelvis i processen att införa SEO i verksamheten. / Studies show that the knowledge and experience of marketing in small and medium-sized enterprises (SMEs) is to a large extent quite poor. There are no guidelines for how SMEs in the construction industry should work with marketing and how companies should consider digitizing marketing in order to reach a larger potential customer group. In addition, it is mentioned that more people are starting to use the internet and in step with this, it is becoming increasingly important for SMEs to keep up with digital developments. Therefore, it is important to examine the factors that influence SME's attitude towards the use of search engine optimization (SEO). Previous studies show that there are a number of factors that affect the attitude of SMEs to use SEO. A few of the studies were written earlier than in 2015 and after the literature search, we find no later studies in the relevant area on what influences the process for the introduction of SEO at SME in the construction industry as a context. Data have been collected through seven interviews with as many companies. Data collection has taken place via digital interviews together with staff who have good insight into the company's strategies for digital consumer impact. Data have then been analyzed through a qualitative content analysis together with previous studies in the field. The results of the study identified three themes which were economics where factors such as financial resources and the attitude of the industry are included. The technical theme with the factors, other digital market channels and faster establishment as well as the theme knowledge where the factor attitude of employees is highlighted. Most of the identified factors are confirmed by what previous research has contributed to while new findings have been made. After an analysis of the factors, we came up to the conclusion that each individual factor can have a direct impact on the choice of SME to introduce SEO as a tool for digital consumer influence. The results also showed that the factors often interact with each other and act alternately in the process of introducing SEO into the business.

Purpose – The purpose of this thesis is contributing to the research on the efficacy of backlinks originating from Web 2.0 blogs by designing a costless method for creating controllable backlinks to a website, solely with Web 2.0 blogs as a source of backlinks. The objective is to find out if such links can provide an effect on a website’s positions in the Google SERPs in 2020 and to hopefully contribute with a controllable link strategy that is available for any SEO practitioner regardless of their economic circumstances. The thesis provides answers to the two research questions: 1. What positions in the SERPs can an already existing website claim as a result of creating and implementing a link strategy that utilizes Web 2.0 blogs? 2. In context of implementing a link strategy, what practices must be considered for it to remain unpunished by Google in 2020? Method – The choice of research method, due to the nature of the project is Design Science Research (DSR), in which the designed artefact is observationally evaluated by conducting a field study. The artefact consists of four unique Web 2.0 blogs that each sent a backlink to the target website through qualitative blog posts following Google’s guidelines. Quantitative data was collected using SERPWatcher by Mangools, which tracked 29 keywords for 52 days, and was qualitatively analysed. Conclusions – There is a distinct relation between the improvement in keyword positions and the implementation of the artefact, leaving us with the conclusion that it is reasonable to believe that Web 2.0 blog backlinks can affect a website’s positions in the SERPs in the modern Google Search. More research experimenting with Web 2.0 blogs as the origin of backlinks must be conducted in order to truly affirm or deny this claim, as an evaluation on solely one website is insufficient. It can be concluded that the target website was not punished by Google after implementation. While their search algorithm may be complex and intelligent, it was not intelligent enough to punish our intentions of manipulating another website’s keyword positions via a link scheme. Passing through as legitimate may have been due to following E-A-T practices and acting natural, but this is mere speculation without comparisons with similar strategies that disregard these practices. Limitations – Rigorous testing and evaluation of the designed artefact and its components is very important when conducting research that employs DSR as a method. Due to time constraints, the lack of data points in form of websites the artefact has been tested on, as well as the absence of iterative design, partially denies the validity of the artefact since it does not meet the criteria of being rigorously tested. The data collected would be more impactful if keyword data were gathered many days before executing the artefact, as a pre-implementation period larger than 7 days would act as a reference point when evaluating the effect. It would also be ideal to track the effects post-implementation for a longer time period due to the slow nature of SEO. Keywords – SEO, search engine optimization, off-page optimization, Google Search, Web 2.0, backlinks.

Un nouveau moteur de recherche embarqué conçu pour les objets intelligents. Ces dispositifs sont généralement équipés d'extrêmement de faible quantité de RAM et une grande capacité de stockage Flash NANAD. Pour faire face à ces contraintes matérielles contradictoires, les moteurs de recherche classique privilégient soit la scalabilité en insertion ou la scalabilité en requête, et ne peut pas répondre à ces deux exigences en même temps. En outre, très peu de solutions prennent en charge les suppressions de documents et mises à jour dans ce contexte. nous avons introduit trois principes de conception, à savoir y Write-Once Partitioning, Linear Pipelining and Background Linear Merging, et montrent comment ils peuvent être combinés pour produire un moteur de recherche intégré concilier un niveau élevé d'insertion / de suppression / et des mises à jour. Nous avons mis en place notre moteur de recherche sur une Board de développement ayant un représentant de configuration matérielle pour les objets intelligents et avons mené de vastes expériences en utilisant deux ensembles de données représentatives. Le dispositif expérimental résultats démontrent la scalabilité de l'approche et sa supériorité par rapport à l'état des procédés de l'art. / A new embedded search engine designed for smart objects. Such devices are generally equipped with extremely low RAM and large Flash storage capacity. To tackle these conflicting hardware constraints, conventional search engines privilege either insertion or query scalability but cannot meet both requirements at the same time. Moreover, very few solutions support document deletions and updates in this context. we introduce three design principles, namely Write-Once Partitioning, Linear Pipelining and Background Linear Merging, and show how they can be combined to produce an embedded search engine reconciling high insert/delete/update rate and query scalability. We have implemented our search engine on a development board having a hardware configuration representative for smart objects and have conducted extensive experiments using two representative datasets. The experimental results demonstrate the scalability of the approach and its superiority compared to state of the art methods.

This project focuses on a system that answers questions formulated in natural language. Firstly, the report discusses problems associated with question answering systems and some commonly employed approaches. Emphasis is laid on shallow methods, which do not require many linguistic resources. The second part describes our work on a system that answers factoid questions, utilizing Czech Wikipedia as a source of information. Answer extraction is partly based on specific features of Wikipedia and partly on pre-defined patterns. Results show that for answering simple questions, the system provides significant improvements in comparison with a standard search engine.

Visma Labs AB or Visma wanted to conduct experiments to see if file metadata could be indexed for searching files on a public cloud storage. Given that storing files in a public cloud storage is cheaper than the current storage solution, the implementation could save Visma money otherwise spent on expensive storage costs. The thesis is therefore to find and evaluate an approach chosen for indexing file metadata and searching files on a public cloud storage with the chosen distributed search engine Elasticsearch. The architecture of the proposed solution is similar to a file service and was implemented using several containerized services for it to function. The results show that the file service solution is indeed feasible but would need further tuning and more resources to function according to the demands of Visma. / Visma Labs AB eller Visma ville genomföra experiment för att se om filmetadata skulle kunna indexeras för att söka efter filer på ett publikt moln. Med tanke på att lagring av filer på ett publikt moln är billigare än den nuvarande lagringslösningen, kan implementeringen spara Visma pengar som spenderas på dyra lagringskostnader. Denna studie är därför till för att hitta och utvärdera ett tillvägagångssätt valt för att indexera filmetadata och söka filer på ett offentligt molnlagring med den utvalda distribuerade sökmotorn Elasticsearch. Arkitekturen för den föreslagna lösningen har likenelser av en filtjänst och implementerades med flera containeriserade tjänster för att den ska fungera. Resultaten visar att filservicelösningen verkligen är möjlig men skulle behöva ytterligare modifikationer och fler resurser att fungera enligt Vismas krav.

This thesis studies the characteristics of data hosted on the interplanetary name system, which is a part of the interplanetary file system. From these records, information such as file names, locations, and sizes, was investigated. Data was collected on the number of peers hosting the records, thereby determining the decentralization of the record on the network. Data on how often content on the network changes, were collected and investigated. In addition to evaluating records, a search engine was prototyped to show how to integrate the data into a system. A large part of the network was crawled and the rate of change was found to be high. Most of the peers were found to host HTML files. Most content identifiers found were hosted by more than one peer. This means that a search engine needs to be able to support text file formats and revisit peers regularly to be up-to-date with the records.

This report describes my work with a website for a company that helps other companies book conferences. Creating this website, I have worked from a Mobile First perspective to create an interface. The interface was then tested on potential users. I then used guidelines from Googles own documentation on search engine optimization. The purpose of this work is to create and deliver a website where users can turn to MH Konferens and let them handle booking and planning of their conferences. / Denna rapport beskriver arbetet med en webbplats för ett företag som jobbar med att boka konferenser åt andra företag. Jag har i framtagandet av webbplatsen utgått från Mobile First och skapat ett gränssnitt. Gränssnittet har sedan testats på användare och slutligen har jag utgått från Googles egen dokumentation för att optimera webbplatsen för sökmotorer. Syftet med arbetet är att skapa en webbplats som leder till att användare kan vända sig till MH konferens och låta dem ta hand om bokning och planering av deras konferenser.
