Traditional\nrelative valuation methods heavily rely on tedious and expensive human efforts, especially for non-publicly listed companies. However,\nthe availability of information about company\u2019s invisible assets, such as patents, talent, and investors, enables a new paradigm to learn\nand evaluate corporate relative values automatically. Indeed, in this paper, we reveal that, the companies and their core members can\nnatually be formed as a heterogeneous graph and the attributes of different nodes include semantically-rich multi-modal data, thereby\nwe are able to extract a latent embedding for each company. The network embeddings can re\ufb02ect domain experts\u2019 behavior and are\neffective for corporate relative valuation.

The com-\nmon method for neighbor sampling is to sample direct\nneighbors of each node, i.e., \ufb01rst-order neighbors. Neverthe-\nless, \ufb01rst-order neighbors have several limitations as men-\ntioned in [19]: 1) Be susceptible to interference. Nodes have\nlimited \ufb01rst-order neighbors, thus noise neighbors with\nincorrect relations or attributes may impair the embedding;\n2) Information loss. The effects of non-direct neighbors are\nlost by aggregating attributes of direct neighbors only, and\nlimited neighbors may lead to insuf\ufb01cient embedding, for\nexample, node A has \ufb01ve direct neighbors while node B only\nhas three; and 3) Aggregation dif\ufb01culty. Sampling direct\nneighbors is unsuitable for aggregating heterogeneous in-\nformation that contains different modal features. Therefore,\nsampling only direct neighbors may play a negative role.\nHeterogeneous neighbors require different transformations\nto deal with various feature types and dimensions.\nTo solve this problem, inspired from [13, 14], HM2uti-\nlizes the random walk sampling for each node.

With the development of\ndata mining technologies, there have been some attempts\nto use related techniques for valuation [35, 36].

Planning changes in an enterprise and its supporting IT\ncan be supported by enterprise architecture (EA) models. The planned\nchanges result in gaps which can be derived by a gap analysis.

The result of such a planning process is a sequence of actions\nchanging a model into another model.\nHowever, graph transformations have the disadvantage that they provide a\nhuge state space regarding the states, which have to be examined when all states\nin the graph are computed. As a consequence this in\ufb02uences the computation\ntime of all possible worlds created through the transformations. With graphtransformations a planning problem can be solved by searching for graph pat-\nterns in a state represented by a graph and applying graph transformations to\nchange the state [ 23]. Graph transformations have the bene\ufb01t that they have a\nsound theoretical foundation [ 24].\n3 From Gaps to Transformation Paths as Sequences\nof Actions\nThe goal of the proposed approach is to deliver a more detailed model of the\ntarget architecture by making suggestions to a domain expert how a detailed\ntarget architecture could look like.

Diefenthaler and B. Bauer\nand relationships in an architecture model and concrete changes to the state of\narchitecture models. The application of a concrete action to an architecturemodel, may enable the application of several other concrete actions.\nAbstract actions are either atomic or composed. An atomic action changes\nexactly one element of either currentArchitecture ortargetArchitecture . Com-\nposed actions are a composition of other actions, regardless if atomic or com-\nposed. To create a transformation path it is necessary to model at least abstract\nactions for shutting down and developing building blocks and abstract actionsthat take care of the relationships between the building blocks and the attributes\nof the building blocks.\nLogical Order of Abstract Actions. The abstract actions are modeled in\na logical order, which means that it is only possible to apply the action if the\npreceding actions were already applied. For example, it is not possible to changethe dependencies from a service to its successor service if it has not yet been\nbuilt. Furthermore, it may be necessary to build the application \ufb01rst to allow the\ncreation of a new service. After the dependencies of a service have been changed\nto a successor it is possible to shutdown the service.\nIf all services of an application have been shutdown it is possible to shutdown\nthe application. The logical order prevents the creation of loops in the transfor-\nmation path, i.e. to shutdown and create the same application several times. It\nmay be the case that it is not necessary to enact the develop application action.\nFor example, if a service which has to be developed for an application that\nalready exists. In this case it is not necessary to develop that application again\nsince it already exists in the current architecture. The logical order prevents theshutdown of the predecessor services, until the successor service is developed.\n3.6 Creating the Transformation Path\nWith the action repository, the transformation model, the models of current\narchitecture and target architecture at hand it is possible to start the creationof possible transformation paths.\nWe derive all applicable concrete actions by checking which preconditions of\nabstract actions match in\nplanningKnowledgeBase :={transf", "start_char_idx": null, "end_char_idx": null, "text_template": "[Excerpt from document]\n{metadata_str}\nExcerpt:\n-----\n{content}\n-----\n", "metadata_template": "{key}: {value}", "metadata_seperator": "\n"}, "__type__": "1"}, "5877d42f-f6c7-4b0c-a003-cc67dd788599": {"__data__": {"id_": "5877d42f-f6c7-4b0c-a003-cc67dd788599", "embedding": null, "metadata": {"page_label": "482", "file_name": "From Gaps to Transformation Paths in Enterprise Architecture Planning.pdf", "file_path": "docs\\From Gaps to Transformation Paths in Enterprise Architecture Planning.pdf", "creation_date": "2023-11-06", "last_modified_date": "2023-10-20", "last_accessed_date": "2023-11-30", "document_title": "Heterogeneous Multi-Modal Graph Neural Network for Corporate Relative Valuation", "questions_this_excerpt_can_answer": "1.

However, most\nGNNs are designed for homogeneous graphs, in which all nodes\nand edges belong to the same types, making them infeasible to\nrepresent heterogeneous structures. In this paper, we present the\nHeterogeneous Graph Transformer (HGT) architecture for mod-\neling Web-scale heterogeneous graphs. To model heterogeneity,\nwe design node- and edge-type dependent parameters to charac-\nterize the heterogeneous attention over each edge, empowering\nHGT to maintain dedicated representations for different types of\nnodes and edges. To handle dynamic heterogeneous graphs, we in-\ntroduce the relative temporal encoding technique into HGT, which\nis able to capture the dynamic structural dependency with arbitrary\ndurations. To handle Web-scale graph data, we design the hetero-\ngeneous mini-batch graph sampling algorithm\u2014HGSampling\u2014for\nefficient and scalable training. Extensive experiments on the Open\nAcademic Graph of 179 million nodes and 2 billion edges show\nthat the proposed HGT model consistently outperforms all the\nstate-of-the-art GNN baselines by 9 %\u201321%on various downstream\ntasks.

In this work, we present the Heterogeneous\nGraph Transformer (HGT) architecture to deal with all these issues.\nTo handle graph heterogeneity, we introduce the node- and edge-\ntype dependent attention mechanism. Instead of parameterizing\neach type of edges, the heterogeneous mutual attention in HGT is\ndefined by breaking down each edge e=(s,t)based on its meta\nrelation triplet, i.e., \u27e8node type of s, edge type of ebetween s&\nt, node type of t\u27e9. Figure 1 illustrates the meta relations of hetero-\ngeneous academic graphs. In specific, we use these meta relations\nto parameterize the weight matrices for calculating attention over\neach edge. As a result, nodes and edges of different types are al-\nlowed to maintain their specific representation spaces.

Next, we introduce the Relative Temporal\nEncoding (RTE) technique for HGT to handle graph dynamic.\nThe traditional way to incorporate temporal information is to\nconstruct a separate graph for each time slot.

Meanwhile, the representation of a node at\ntime tmight rely on edges that happen at other time slots. There-\nfore, a proper way to model dynamic graphs is to maintain all the\nedges happening at different times and allow nodes and edges with\ndifferent timestamps to interact with each other.\nIn light of this, we propose the Relative Temporal Encoding\n(RTE) mechanism to model the dynamic dependencies in heteroge-\nneous graphs. RTE is inspired by Transformer\u2019s positional encoding\nmethod [ 15,21], which has been shown successful to capture the\nsequential dependencies of words in long texts.\nSpecifically, given a source node sand a target node t, along\nwith their corresponding timestamps T(s)andT(t), we denote the\nrelative time gap \u2206T(t,s)=T(t)\u2212T(s)as an index to get a relative\ntemporal encoding RT E(\u2206T(t,s)).

To address this issue, different sampling-based methods [ 1,\n2,7,29] have been proposed to train GNNs on a subset of nodes.\nHowever, directly using them for heterogeneous graphs is prone to\nget sub-graphs that are extremely imbalanced regarding different\nnode types, due to that the degree distribution and the total number\nof nodes for each type can vary dramatically.\nTo address this issue, we propose an efficient Heterogeneous\nMini-Batch Graph Sampling algorithm\u2014HGSampling\u2014to enable\nboth HGT and traditional GNNs to handle Web-scale heterogeneous\ngraphs. HGSampling is able to 1) keep a similar number of nodes\nand edges for each type and 2) keep the sampled sub-graph dense\nto minimize the information loss and reduce the sample variance.\nAlgorithm 1 outlines the HGSampling algorithm. Its basic idea\nis to keep a separate node budget B[\u03c4]for each node type \u03c4and\nto sample an equal number of nodes per type with an importance\nsampling strategy to reduce variance. Given node talready sampled,\nwe add all its direct neighbors into the corresponding budget with\nAlgorithm 2, and add t\u2019s normalized degree to these neighbors in\nline 8, which will then be used to calculate the sampling probability.\nSuch normalization is equivalent to accumulate the random walk\nprobability of each sampled node to its neighborhood, avoiding the\nsampling being dominated by high-degree nodes. Intuitively, the\nhigher such value is, the more a candidate node is correlated with\nthe currently sampled nodes, and thus should be given a higher\nprobability to be sampled.\n\u2217For simplicity, we denote a linear projection L :Ra\u2192Rbas a function to conduct\nlinear transformation to vector x\u2208Raas: L(x)=W x+b,", "start_char_idx": null, "end_char_idx": null, "text_template": "[Excerpt from document]\n{metadata_str}\nExcerpt:\n-----\n{content}\n-----\n", "metadata_template": "{key}: {value}", "metadata_seperator": "\n"}, "__type__": "1"}, "6a2ab275-5181-4cc2-b554-cc30e92ebb1d": {"__data__": {"id_": "6a2ab275-5181-4cc2-b554-cc30e92ebb1d", "embedding": null, "metadata": {"page_label": "6", "file_name": "Heterogeneous Graph Transformer.pdf", "file_path": "docs\\Heterogeneous Graph Transformer.pdf", "creation_date": "2023-11-06", "last_modified_date": "2023-10-20", "last_accessed_date": "2023-11-30", "document_title": "Heterogeneous Multi-Modal Graph Neural Network for Corporate Relative Valuation", "questions_this_excerpt_can_answer": "1.
