    „Slepo poverenje“:

    • Se ne preporučuje ali postoji

    • Je poverenje kod koga je potpuno poznat ishod pre izvršene akcije

    • Se zasniva na prethodnom iskustvu

    • Je isto što i apsolutno poverenje

    Correct Answer

    Most je (u analizi društvenih mreža grafovima):

    • Čvor koji ima najveću sopstvenu centralnost

    • Čvor koji povezuje 2 klastera

    • Veza koja povezuje 2 klastera

    • Čvor koji ima najveći betweenness centrality

    Correct Answer
    A. Veza koja povezuje 2 klastera
    Explanation
    The correct answer is "Veza koja povezuje 2 klastera" because in the analysis of social networks using graphs, a "cluster" refers to a group of nodes that are densely connected to each other but sparsely connected to nodes outside the cluster. Therefore, a link that connects two clusters would be a connection between two distinct groups within the network.

    • Homofilija

    • Tranzitivnost

    • Reciprocitet

    • Simelijeve veze

    Correct Answer
    A. Homofilija
    Explanation
    Homofilija refers to the tendency of nodes to connect with nodes that have similar characteristics. In other words, nodes in a network are more likely to form connections with other nodes that share similar attributes or traits. This can be observed in various social networks where individuals with similar interests, backgrounds, or characteristics tend to form connections with each other. Homofilija plays a significant role in shaping the structure and dynamics of social networks, as it contributes to the formation of clusters or communities within the network.

    U usmerenoj mreži od n čvorova broj mogućih ivica je:

    • N*(n-1)

    • N*(n-1)/2

    • 2 n*(n-1)/2

    • 2*n*(n-1)

    Correct Answer
    A. N*(n-1)
    Explanation
    In a directed network with n nodes, the number of possible edges is given by n*(n-1). This is because for each node, there are n-1 possible edges that can be connected to other nodes. Therefore, multiplying the number of nodes by the number of possible edges for each node gives us the total number of possible edges in the network.

    • Samo odnose

    • Samo stavove i vrednosti koje upravljaju međuljudskim interakcijama

    Correct Answer
    A. Sve nabrojano
    Explanation
    The correct answer is "Sve nabrojano" because social capital refers to the networks, relationships, and norms of a society that enable cooperation and facilitate collective action. This includes institutions, relationships, attitudes, and values that govern interpersonal interactions. Therefore, all the options listed (institutions, relationships, attitudes/values) are components of social capital.

    Šta važi za poverenje i uverenje:

    • Iz uverenja može da se izračuna poverenje

    • Poverenje i uverenje su isti pojmovi

    • Poverenje i uverenje su dva različita pojma

    • Iz poverenja može da se izračuna uverenje

    Correct Answer
    A. Poverenje i uverenje su dva različita pojma
    Explanation
    The correct answer is "Poverenje i uverenje su dva različita pojma." This answer states that trust and belief are two different concepts. This is supported by the fact that the statement "Iz uverenja može da se izračuna poverenje" (Trust can be calculated from belief) implies that trust and belief are not the same thing. Therefore, the answer correctly identifies that trust and belief are two distinct concepts.

    • Veza koja povezuje dva klastera

    • Čvor koji povezuje dva klastera

    Correct Answer
    A. Čvor koji povezuje dva klastera
    Explanation
    A broker in social network analysis refers to a node that connects two or more clusters. Clusters are groups of nodes that are densely connected within themselves but have fewer connections between them. Therefore, a broker acts as a bridge between different clusters, facilitating communication and information flow between them. This concept is important in understanding network dynamics and identifying influential nodes in a social network.

    Klikovi su:

    • Slabo povezane mreže

    • Slabo povezani klasteri

    • Potpuno povezani klasteri

    • Trijade

    Correct Answer
    A. Potpuno povezani klasteri
    Explanation
    The answer "Potpuno povezani klasteri" is correct because it refers to fully connected clusters. In a fully connected cluster, every node is directly connected to every other node within the cluster. This means that there are no isolated nodes or disconnected subgroups within the cluster. In contrast, "Slabo povezane mreže" refers to loosely connected networks, "Slabo povezani klasteri" refers to loosely connected clusters, and "Trijade" refers to a concept in social network analysis.

    Fenomen malog sveta je teza koja kaže da:

    • Se do svake osobe može doći preko lanca društvenih poznanstava dužine 6

    • Se do svake osobe može doći preko kratkog lanca društvenih poznanstava

    • Da se do svake osobe može doći preko neke društvene mreže

    • Je svaka društvena mreža gusta

    Correct Answer
    A. Se do svake osobe može doći preko kratkog lanca društvenih poznanstava
    Explanation
    The correct answer suggests that it is possible to reach any person through a short chain of social acquaintances. This concept is known as the "small world phenomenon" or "six degrees of separation." It implies that within a social network, individuals are connected to each other through a relatively small number of intermediaries. This idea gained popularity after the famous "Milgram experiment" in the 1960s, where participants were asked to send a message to a target person through their social contacts, and it was found that the average number of intermediaries was around six.

    • Matrica susedstva

    Correct Answer
    A. Matrica susedstva
    Explanation
    The correct answer is "Matrica susedstva". The image shows a representation of a graph, where each node is connected to its adjacent nodes through edges. The matrix representation of this graph, known as the adjacency matrix or "Matrica susedstva" in Serbian, is a square matrix that indicates the connections between nodes. Each element in the matrix represents whether there is an edge between two nodes or not. This matrix is commonly used in graph theory and various algorithms for analyzing and manipulating graphs.

    Poverenje se različito ocenjuje od strane različitih ljudi što znači da je poverenje kao pojava:

    • Kompozitno

    • Subjektivno

    • Merljivo

    • Relevantno

    Correct Answer
    A. Subjektivno
    Explanation
    Poverenje se različito ocenjuje od strane različitih ljudi, što znači da je poverenje kao pojava subjektivno. Subjektivno znači da je ocena poverenja zavisna od individualnih stavova, mišljenja i percepcija svakog pojedinca. Ovo znači da ne postoji objektivno merenje ili standard za procenu poverenja, već je to lična procena svakog pojedinca.

    Kod Pirsonovog koeficijenta, što je vrednost bliža -1 to znači da:

    • Su korisnici/artikli sličniji

    • Se korisnici/artikli više razlikuju

    • Da artikal/korisnika ne treba preporučiti

    • Da artikal/korisnika treba preporučiti

    Correct Answer
    A. Se korisnici/artikli više razlikuju
    Explanation
    When the value of the Pearson correlation coefficient is closer to -1, it means that the users/items are more dissimilar. This suggests that there is a negative correlation between the users/items, indicating that they have different preferences or characteristics. Therefore, the correct answer is "Se korisnici/artikli više razlikuju" which translates to "The users/items are more dissimilar".

    Ukoliko grafu društvene mreže želi da se doda i podatak o broju razmenjenih poruka između 2 čvora u nekom vremenskom periodu, onda se on dodaje preko:

    • Težine ivice

    • Izlaznog stepena čvora

    • Zbira ulaznog i izlaznog stepena čvora

    • Reciprociteta

    Correct Answer
    A. Težine ivice
    Explanation
    The correct answer is "Težine ivice" (weight of the edge). When adding the information about the number of exchanged messages between two nodes in a social network graph, it is done through the weight of the edge connecting those nodes. The weight represents the strength or intensity of the relationship between the nodes, in this case, the number of messages exchanged.

    • Graf

    • Stepen čvora

    Correct Answer
    A. Lista ivica grafa
    Explanation
    The correct answer is "Lista ivica grafa" because the image represents a graphical representation of a graph, where the edges are represented by a list of pairs of vertices. This is commonly known as an edge list or lista ivica in Serbian. The other options, such as "Matrica susedstva" (adjacency matrix), "Graf" (graph), and "Stepen čvora" (degree of a vertex), do not accurately describe the representation shown in the image.

    Podela na asinhrono i sinhrono učenje vezana je za:

    • Vreme korišćenja alata za učenje

    • Mesto korišćenja alata za učenje

    • Vrstu alata za učenje

    • Način korišćenja alata za učenje

    Correct Answer
    A. Vreme korišćenja alata za učenje
    Explanation
    The correct answer is "Vreme korišćenja alata za učenje" which translates to "Time of using learning tools" in English. This suggests that the division between asynchronous and synchronous learning is related to the time period during which learning tools are used. Asynchronous learning refers to learning that takes place at different times, allowing learners to access materials and complete tasks at their own pace. On the other hand, synchronous learning occurs in real-time, with learners engaging in activities and discussions simultaneously. Therefore, the time of using learning tools determines whether the learning is asynchronous or synchronous.
